Is there easy way to grid search without cross validation in python? : <p>There is absolutely helpful class GridSearchCV in scikit-learn to do grid search and cross validation, but I don't want to do cross validataion. I want to do grid search without cross validation and use whole data to train.
To be more specific, I need to evaluate my model made by RandomForestClassifier with "oob score" during grid search.
Is there easy way to do it? or should I make a class by myself?</p>
<p>The points are</p>
<ul>
<li>I'd like to do grid search with easy way.</li>
<li>I don't want to do cross validation.</li>
<li>I need to use whole data to train.(don't want to separate to train data and test data)</li>
<li>I need to use oob score to evaluate during grid search.</li>
</ul>

Average of a numpy array returns NaN : <p>I have an np.array with over 330,000 rows. I simply try to take the average of it and it returns NaN. Even if I try to filter out any potential NaN values in my array (there shouldn't be any anyways), average returns NaN. Am I doing something totally wacky? </p>
<p>My code is here: </p>
<pre><code>average(ngma_heat_daily)
Out[70]: nan
average(ngma_heat_daily[ngma_heat_daily != nan])

but unfortunately i don't know how to do the code. i would like to see one

Approaches to improve chart eficiency in C# winforms? : I have a simple chart that prints values read by a photoresistor. Also the chart prints 2 thresholds. My problem is that when more than 300 or 400 points are printed in the chart, it becomes quite unreadable. Look at this:
[![enter image description here][1]][1]
I thought that using an incremental counter and doing this:
if (i > 300) {
chart1.Invoke(new Action(() => {chart1.Series[0].Points.Clear(); }));
chart1.Invoke(new Action(() => { chart1.Series[1].Points.Clear(); }));
chart1.Invoke(new Action(() => { chart1.Series[2].Points.Clear(); }));
i = 0;
}
The problem is solved as my chart becomes empty and readable again, but I don't want to clear and lose all my previous data.
What alternative solutions can I try so my data won't be deleted, but keeping my chart readable?

C# Threading Read Write locks : <p>Hi what will be the cleanest solution for the following pattern ?</p>
<p>Given a class for Read and Write some file/resouce, providing already implemented "read()" and "write()" functions. Create a "Read()" and "Write()" function that would wrap the "read()" and "write()"and prevent threads from interfering as follows:</p>
<p>a. multiple threads are allowed to Read</p>
<p>b. Only one thread is allowed to Write - so if a thread is already writing the other threads must wait.</p>
<p>c. writing must be prevented while a thread is reading and vice versa</p>

cannot update identity column in Entity Framework Core : <p>I've added a separate Identification to the AspNetUsers table called NumericId that will serve along with the GUID like ID that ASP has for default.</p>
<p>I've added the property as an additional property of the ApplicationUser class:</p>
<pre><code>public class ApplicationUser : IdentityUser
{
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public virtual int NumericId { get; set; }
}
</code></pre>
<p>However, when I try to register, or update the user's details (that aren't even relevant to the numericId) I keep getting the error </p>
<pre><code>SqlException: Cannot update identity column 'NumericId'.
</code></pre>
<p>which prevents any changes and in the end does not update the user (but it does register one, and Numeric Id is properly assigned on that part. But this is irrelevant)</p>

Lumen middleware sort (priority) : <p>I'm using <code>"laravel/lumen-framework": "5.7.*"</code></p>
<p>I have two middlewares, first one <code>AuthTokenAuthenticate</code> that should be applied to all the routes, so its defined in <code>bootstrap/app.php</code> like</p>
<pre><code>$app->middleware([
App\Http\Middleware\AuthTokenAuthenticate::class
]);
</code></pre>
<p>Another middleware is defined like </p>
<pre><code>$app->routeMiddleware([
'auth.token' => Vendor\Utilities\Middleware\AuthToken::class
]);
</code></pre>
<p>and will only be applied to some specific routes.</p>
<p>I need <code>auth.token</code> to be executed first, then <code>AuthTokenAuthenticate</code> but I can't find the way to do it because Lumen executes <code>$app->middleware</code> routes first. </p>
<p>Laravel has <code>$middlewarePriority</code> which is exactly what I need, but how can I handle it in Lumen? </p>

MySQL - SELECT COUNT(*) AND IGNORE SAME ID : <p>As per the title, I want to count rows in a table but if multiple rows got same ID, should count them as ONE ROW.</p>
<p>For example, I have a table named <code>my_table</code>.</p>
<p>And below is the data:</p>
<p><a href="https://i.stack.imgur.com/cpC3n.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cpC3n.png" alt="enter image description here"></a></p>
<p>Ok, let's say if I run this query: <code>SELECT COUNT(*) AS cnt FROM my_table;</code></p>
<p>the result will be
<code>cnt = 6</code> ..</p>
<p>But I don't want that.</p>
<p>What I want to achieve is the <code>cnt</code> should be <code>4</code> because multiple rows with SAME ID should be counted as ONE..</p>
<p>p/s: Sorry for my bad english language..</p>

Enable and disable dates jquery using datepicker : <p>I am using the jquery datepicker. I have set an array of dates which should be disabled, this is working fine:</p>
<pre><code> var vakantie = ["25-12-2018", "26-12-2018", "27-12-2018", "28-12-2018", "29-12-2018", "30-12-2018", "31-12-2018"];
function nietBeschikbaar(dt){
var datestring = jQuery.datepicker.formatDate('dd-mm-yy', dt);
return [dt.getDay() == 1 || dt.getDay() == 2 ? false : true && vakantie.indexOf(datestring) == -1 ];
};
jQuery("#datepicker").datepicker("option", "beforeShowDay", nietBeschikbaar);
</code></pre>
<p>Now I would also want one date to be enabled (every monday and tuesday is also disabled, but this date is on a monday). With this code I can disable everything except this one date:</p>
<pre><code> var enableDays = ["24-12-2018"];
function enableAllTheseDays(date) {
var sdate = $.datepicker.formatDate( 'dd-mm-yy', date)
if($.inArray(sdate, enableDays) != -1) {
return [true];
}
return [false];
}
jQuery("#datepicker").datepicker("option", "beforeShowDay", enableAllTheseDays);
</code></pre>
<p>But now I would like to combine these two scripts, so I would like to disable the 'vakantie' array, and also enable the 'enableDays' array. I can't get them working togheter, could anyone help me out?</p>

Google Rio 2016 Like Animation : <p>I'm currently building a new website, in which I would like to corporate something that Google is doing as well with some of their widgets (I'm sure other websites do as well.) </p>
<p>I would like to have the website to have an animation to another tab, a little like the Google GIF I included. I know how to do the animation, but it has to get to another tab without having to go to another tab while it shouldn't be clear it's reloading, which I don't know how to do. </p>
<p>Do any of you have any idea which framework or something I have to use? Should I use jQuery, or what else? I can look things up myself, but I would like to know how to get started with it, since I have no idea...</p>

foo = let x = Nothing in (x,x)

<p>Since each component is bound to the same variable <code>x</code>, I would expect that the most general type for this expression to be <code>(Maybe a, Maybe a)</code>. I get the same results if I use a <code>where</code> instead of a <code>let</code>. Am I missing something?</p>

Basic Python syntax error for less than symbol : <p>Hi I'm learning python and I'm stuck making an age calculator. </p>
<p>I have to make an age calculator where it asks the user to enter their age in years and if the user is 100 or older, it tells them "You've already turned 100!". Otherwise, if they are less than 0, tell them "Try again when you are born!". If neither of these are the case, calculate the number of years until they turn 100 and output the message "You will be 100 in x years!" (Where "x" is replaced by the number of years before they turn 100). I must use an if/elif/else statement for this problem.</p>

Are there some pre-trained LSTM, RNN or ANN models for time-series prediction? : <p>I am trying to solve a time series prediction problem. I tried with ANN and LSTM, played around a lot with the various parameters, but all I could get was 8% better than the persistence prediction.</p>
<p>So I was wondering: since you can save models in keras; are there any pre-trained model (LSTM, RNN, or any other ANN) for time series prediction? If so, how to I get them? Are there in Keras?</p>
<p>I mean it would be super useful if there a website containing pre trained models, so that people wouldn't have to speent too much time training them..</p>
<p>Similarly, another question:</p>
<p>Is it possible to do the following?
1. Suppose I have a dataset now and I use it to train my model. Suppose that in a month, I will have access to another dataset (corresponding to same data or similar data, in the future possibly, but not exclusively). Will it be possible to continue training the model then? It is not the same thing as training it in batches. When you do it in batches you have all the data in one moment.
Is it possible? And how?</p>

Please help me to understand the logic behind the assignment of variables : I am a newbie,I want to explore all the methods through which I can assign an operator
I tried many, in some I got error and some succeed,I am sharing the failed methods please help me with their explanations and logic
Method 1
#include <stdio.h>
int main(void) {
int a=b=c=6;
printf("%d\n",a);
printf("%d\n",b);
printf("%d\n",c);
return 0;
}
It displays an error:
prog.c:5:7: error: ‘b’ undeclared (first use in this function)
int a=b=c=6;
^
prog.c:5:7: note: each undeclared identifier is reported only once for
each function it appears in
prog.c:5:9: error: ‘c’ undeclared (first use in this function)
int a=b=c=6;
^
Method 2:
#include <stdio.h>
int main(void) {
int a,b,c;
printf("%d\n",a);
printf("%d\n",b);
printf("%d\n",c);
return 0;
}
My output is
0
0
0
Is this due to return 0?
Also , please add examples for better understanding, I will be thankful to you.

how to sort an array that contain second order in python? : for instance, I have an array like:
[[1,1,0],[1,0,1],[0,0,0]
first to sort the first element, and then if the first element are same ,sort the second element, and then if the second elements are same sort for third, forth....
the result should like this:
[[0,0,0],[1,0,1],[1,1,0]
obviously, the `sorted` function cannot solve this problem easily even if use `key=...`

<p>When I run it, the value 50 is printed instead of the expected value 2. I suppose this happens because the lambda function captures the current <code>this</code> pointer. After the move operation the <code>this</code> pointer changes and the function writes to the wrong <code>a</code>.</p>
<p><strong>Now my question is:</strong> Is there a way to change the lambda's captured reference to the new <code>Test</code> so that the value 2 is printed?</p>

Can't install JDK 9 because "Another Java installation is in progress" : <p>I have been using JDK 9 on Windows 10 x64 for a while but when I went to install the latest early release (b174), I first uninstalled the previous version (as usual) and then ran the new installer.</p>
<p>It fails with a message box saying "Another Java installation is in progress. You must complete that installation before you can run this installer".</p>
<p>It seems there are some artifacts around causing the problem but only for JDK 9 as I can uninstall & reinstall JDK 8 without any issues. Also, the same problem occurs if I try to run the installers for any prior JDK 9 releases as well (even though they worked before).</p>
<p>Searches have suggested various options like using a Microsoft MSI clean-up tool and registry hacks but nothing is helping.</p>
<p>Can anyone suggest a way to get JDK 9 installed (as now I cannot use any release of JDK 9 at all)?</p>

How to divide between groups of rows using dplyr? : <p>I have this dataframe:</p>

# name condition value
# 1 a A 2
# 2 a B 10
# 3 b A 4
# 4 b B 20
# 5 c A 8
# 6 c B 40
# 7 d A 20
# 8 d B 100
</code></pre>
<p>I want to group by name and divide the value of rows with <code>condition == "B"</code> with those with <code>condition == "A"</code>, to get this:</p>
<pre><code>data.frame(
name = letters[1:4],
value = c(5,5,5,5)
)
# name value
# 1 a 5
# 2 b 5
# 3 c 5
# 4 d 5
</code></pre>
<p>I know something like this can get me pretty close: </p>
<pre><code>x$value[which(x$condition == "B")]/x$value[which(x$condition == "A")]
</code></pre>
<p>but I was wondering if there was an easy way to do this with dplyr (My dataframe is a toy example and I got to it by chaining multiple <code>group_by</code> and <code>summarise</code> calls).</p>

Need help writing first VBA code : New to VBA and am in over my head.
I have a table. I would like to write a code that loops through and if the active cell contains a 1, then, in a cell outside of the table, the column heading is returned and put into a comma separated list.
I am looking for that loop to continue all the way across the first row cell by cell, and comma separated list to build with each TRUE return.
Once the loop hits the end of the row I need it to drop down to the next row and continue the same process (but creating its own comma separated list for those that returned true in row 2).
Any help would be greatly appreciated.
I know I need to somehow loop and if statement but just can't figure it out right now.
Thanks

What is the point of StyleSheet.create : <p>I'm reading the <a href="https://facebook.github.io/react-native/docs/style.html#content" rel="noreferrer">React Native docs / tutorial</a>, and I'm wondering what the point of the <code>StyleSheet.create</code> function is.</p>
<p>For example, the tutorial has the following code:</p>
<pre><code>const styles = StyleSheet.create({
bigblue: {
color: 'blue',
fontWeight: 'bold',
fontSize: 30,
},
red: {
color: 'red',
},
});
</code></pre>
<p>But I don't understand the difference between that and:</p>
<pre><code>const styles = {
bigblue: {
color: 'blue',
fontWeight: 'bold',
fontSize: 30,
},
red: {
color: 'red',
},
};
</code></pre>

Is there a way to run a function as long as an array is non zero in size? : <p>Say for example my function woof() clears some array called meow[] by removing the items in it. meow[] may have items added to it by other functions, but as long as it has items in it, ie it's size is nonzero, I want woof to run and clear it. </p>
<p>How do I do this in C++?</p>

Can't open some html files in chrome (mac) : <p>There are some HTML files (no pattern that I've figured out) that I can't open via the terminal, GUI or right clicking Open in Browser via Sublime Text 3. </p>
<p>The default browser to open the file is definitely set to Chrome. When I say to open the file in the browser it takes me to the Chrome window, but doesn't actually open the file I want.</p>
<p>I can open these files in Chrome itself via command + O and in Firefox or Safari by right clicking on the file and selecting them in the GUI.</p>
<p>It'd be great if Chrome would open files when I expect it to. I'd appreciate any help.</p>

Try-with-resource autoclose issues : <p>I am working with a legacy code, where I see certain DB transaction initiated in try-with-Resources close block. I understand the DB resource will be closed once the code in the try block is executed. Can somebody help me, how can I over-ride or bypass the autoclosing, in this case ? I am working with the legacy code and that too for very short time, so want not to change too much of code, and invite unit tests failures.</p>
