write me a code follow example "This Python code implements a chatbot using the GPT-2 language model. The chatbot prompts the user for input, and generates a response based on the input using the GPT-2 model. The chatbot uses the Transformers library to load a pre-trained GPT-2 model and tokenizer. The model generates responses using a beam search algorithm to optimize for the most likely sequence of words. The chatbot also uses a loop to continue the conversation until the user types "exit", "quit", "goodbye", or "bye". The chatbot can be customized by changing the maximum length of the generated response, the number of beams in the beam search algorithm, and the size of the n-gram used for early stopping.

сохранение изменений в профиле не работает. кроме того, При загрузке аудиофайла в профиле в модальном окне профиля пользователя ничего не происходит. Я жму “upload track” и ничего не происходит. База данных tracks не пополняется, папка с треками тоже пустая, как и картинки для альбома не загружаются. проанализируй код, в первую очередь app.js, исправь проблему. так же я получаю ошибку 10:165 Uncaught TypeError: Cannot read properties of null (reading ‘addEventListener’)

База данных tracks не пополняется, папка с треками track тоже пустая. проанализируй код и исправь проблему. p.s: после попытки загрузить файл url меняется на такой, но при этом ни файла, ни картинки ничего нет физически:

so i have this code that toke an image of handwritten non cursive lines text and segment it into lines word characters, and as you can see it give an list of characters but i want it to give a text as it gived in the images line by line and word by word you can modifier whatever you want the dataset containing handwritten images in size 2828 pixels also I observe is not work well to segment lines

For the purposes of this interview, imagine that we own a store. This
store doesn't always have customers shopping: there might be some long
stretches of time where no customers enter the store. We've asked our
employees to write simple notes to keep track of when customers are
shopping and when they aren't by simply writing a single letter every
hour: 'Y' if there were customers during that hour, 'N' if the store
was empty during that hour.
For example, our employee might have written "Y Y N Y", which means
the store was open for four hours that day, and it had customers
shopping during every hour but its third one.
hour: | 1 | 2 | 3 | 4 |
log: | Y | Y | N | Y |
^
|
No customers during hour 3
We suspect that we're keeping the store open too long, so we'd like to
understand when we *should have* closed the store. For simplicity's
sake, we'll talk about when to close the store by talking about how
many hours it was open: if our closing time is `2`, that means the
store would have been open for two hours and then closed.
hour: | 1 | 2 | 3 | 4 |
log: | Y | Y | N | Y |
closing_time: 0 1 2 3 4
^ ^
| |
before hour #1 after hour #4
(A closing time of 0 means we simply wouldn't have opened the store at
all that day.)
First, let's define a "penalty": what we want to know is "how bad
would it be if we had closed the store at a given hour?" For a given
log and a given closing time, we compute our penalty like this:
+1 penalty for every hour that we're *open* with no customers
+1 penalty for every hour that we're *closed* when customers would have shopped
For example:
hour: | 1 | 2 | 3 | 4 | penalty = 3:
log: | Y | Y | N | Y | (three hours with customers after closing)
penalty: | * | * | | * |
^
|
closing_time = 0
hour: | 1 | 2 | 3 | 4 | penalty = 2:
log: | N | Y | N | Y | (one hour without customers while open +
penalty: | * | | | * | one hour with customers after closing)
^
|
closing_time = 2
hour: | 1 | 2 | 3 | 4 | penalty = 1
log: | Y | Y | N | Y | (one hour without customers while open)
penalty: | | | * | |
^
|
closing_time = 4
Note that if we have a log from `n` open hours, the `closing_time`
variable can range from 0, meaning "never even opened", to n, meaning
"open the entire time".
1)
Write a function `compute_penalty` that computes the total penalty, given
a store log (as a space separated string) AND
a closing time (as an integer)
In addition to writing this function, you should use tests to
demonstrate that it's correct. Do some simple testing, and then quickly
describe a few other tests you would write given more time.
Write another function named `find_best_closing_time` that returns
the best closing time in terms of `compute_penalty` given just a
store log. You should use your answer from pt1 to solve this problem.
Again, you should use tests to demonstrate that it's correct. Do
some simple testing, and then quickly describe a few other tests
you would write given more time.
We've asked our employees to write their store logs all together in the
same text file, marking the beginning of each day with `BEGIN` and the
end of each day as `END`, sometimes spanning multiple lines. We hoped
that the file might look like
"BEGIN Y Y END \nBEGIN N N END"
which would represent two days, where the store was open two hours
each day. Unfortunately, our employees are often too busy to remember
to finish the logs, which means this text file is littered with
unfinished days and extra information scattered throughout. Luckily,
we know that an unbroken sequence of BEGIN, zero or more Y's or N's,
and END is going to be a valid log, so we can search the aggregate log
for those.
For example, given the aggregate log:
"BEGIN BEGIN BEGIN N N BEGIN Y Y END N N END"
^ ^
| |
+-----------+
valid log
In this example, We can extract only one valid log, "BEGIN Y Y END". For our
purposes, we should ignore any invalid log. *A valid log cannot contain a
nested log. (i.e. Valid logs cannot be nested.) Valid logs can span multiple lines.
Also there can be multiple valid logs on a single line.*
Write a function `get_best_closing_times` that takes an aggregate log
as a string and returns an array of best closing times for every valid
log we can find, in the order that we find them.
Again, you should use tests to demonstrate that it's correct. Do
some simple testing, and then quickly describe a few other tests
you would write given more time.
Over time these aggregate log files can get very large, so write
another function, `get_best_closing_times__v2`. This should work like
the previous one, but with two important differences:
- Instead of accepting an aggregate log as a string, it should
accept a *filename* (and *not* the contents of the file.)
- It should take care *not to read the whole file's contents at
once*, and instead should stream the file as it goes. Assume that
the whole file is too large to fit in memory. (You can, however,
safely assume that each individual line of the file can fit in
memory.)
In all other respects, this function should behave like
`get_best_closing_times`, finding the valid log sequences and
returning an array of the best closing times corresponding to each.

во-первых, мне нужно установить ограничение на формат загружаемых аудиофайлов - это должен быть только .mp3. во-вторых, должно стоять ограничение на размер загружаемых файлов (подумай, какое значение было бы оптимальным и выстави его сам). в третьих, плеер в profile.ejs криво расположен, он идет справа от названия и корежит весь сайт. Желательно если бы немного придали красоты плееру. В четвертых, для загружаемых .mp3 файлов должно стоять какое-то сжатие, чтобы сжимать файлы для экономии места.

а можешь добавить к этому коду на Skript
команду /random off которая отключает эти рандомные предметы самому себе и /random on которая включает рандомные предметы самому себе когда ты отключаешь у тебя в actionbar будет написано на 5 секунд сообщение и потом оно пропадет красным "Вы отключили рандомные предметы" а когда включает всё также но зеленок сообщение "Вы включили предметы". Важно чтоб /random off/on отключали или включали только для игрока который выполнил команду
Вот код:
options:
countdown_1: 30 # Задержка с 1 до 15 игроков
countdown_2: 45 # Задержка с 16 до 228 игроков
itemGivenDisplayTime: 1
every 1 seconds:
loop all players:
# Получаем количество игроков на сервере
set {_player_count} to size of all players
# Устанавливаем задержку в зависимости от количества игроков
if {_player_count} <= 15:
set {_countdown} to {@countdown_1}
else if {_player_count} <= 228:
set {_countdown} to {@countdown_2}
else:
stop
# Отсюда идет остальной код
if {timer.%loop-player%} is not set:
set {timer.%loop-player%} to 0
if {changed.%loop-player%} is not set:
set {changed.%loop-player%} to 0
if {timer.%loop-player%} is not {_countdown}:
if {changed.%loop-player%} <= 0:
send action bar "&x&8&d&f&b&0&0⛏ ᴘᴀʜдᴏᴍ пᴘᴇдмᴇт: &f%{_countdown} - {timer.%loop-player%}% ᴄᴇᴋyʜд" to loop-player
else:
subtract 1 from {changed.%loop-player%}
else:
set {timer.%loop-player%} to 0
