+# `gradio_client`: Use a Gradio app as an API -- in 3 lines of Python
+
+This directory contains the source code for `gradio_client`, a lightweight Python library that makes it very easy to use any Gradio app as an API. 
+
+As an example, consider this [Hugging Face Space that transcribes audio files](https://huggingface.co/spaces/abidlabs/whisper) that are recorded from the microphone.
+
+![](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/gradio-guides/whisper-screenshot.jpg)
+
+Using the `gradio_client` library, we can easily use the Gradio as an API to transcribe audio files programmatically.
+
+Here's the entire code to do it:
+
+```python
+from gradio_client import Client
+
+client = Client("abidlabs/whisper") 
+client.predict("audio_sample.wav")  
+
+>> "This is a test of the whisper speech recognition model."
+```
+
+The Gradio client works with any Gradio Space, whether it be an image generator, a stateful chatbot, or a tax calculator.
+
+## Installation
+
+If you already have a recent version of `gradio`, then the `gradio_client` is included as a dependency. 
+
+Otherwise, the lightweight `gradio_client` package can be installed from pip (or pip3) and works with Python versions 3.8 or higher:
+
+```bash
+$ pip install gradio_client
+```
+
+## Basic Usage
+
+### Connecting to a Space or a Gradio app
+
+Start by connecting instantiating a `Client` object and connecting it to a Gradio app that is running on Spaces (or anywhere else)!
+
+**Connecting to a Space**
+
+```python
+from gradio_client import Client
+
+client = Client("abidlabs/en2fr")  # a Space that translates from English to French
+```
+
+You can also connect to private Spaces by passing in your HF token with the `hf_token` parameter. You can get your HF token here: https://huggingface.co/settings/tokens
+
+```python
+from gradio_client import Client
+
+client = Client("abidlabs/my-private-space", hf_token="...") 
+```
+
+**Duplicating a Space for private use**
+
+While you can use any public Space as an API, you may get rate limited by Hugging Face if you make too many requests. For unlimited usage of a Space, simply duplicate the Space to create a private Space,
+and then use it to make as many requests as you'd like!
+
+The `gradio_client` includes a class method: `Client.duplicate()` to make this process simple:
+
+```python
+from gradio_client import Client
+
+client = Client.duplicate("abidlabs/whisper") 
+client.predict("audio_sample.wav")  
+
+>> "This is a test of the whisper speech recognition model."
+```
+
+If you have previously duplicated a Space, re-running `duplicate()` will *not* create a new Space. Instead, the Client will attach to the previously-created Space. So it is safe to re-run the `Client.duplicate()` method multiple times. 
+
+**Note:** if the original Space uses GPUs, your private Space will as well, and your Hugging Face account will get billed based on the price of the GPU. To minimize charges, your Space will automatically go to sleep after 1 hour of inactivity. You can also set the hardware using the `hardware` parameter of `duplicate()`.
+
+
+**Connecting a general Gradio app**
+
+If your app is running somewhere else, just provide the full URL instead, including the "http://" or "https://". Here's an example of making predictions to a Gradio app that is running on a share URL:
+
+```python
+from gradio_client import Client
+
+client = Client("https://bec81a83-5b5c-471e.gradio.live")
+```
+
+
+### Inspecting the API endpoints
+
+Once you have connected to a Gradio app, you can view the APIs that are available to you by calling the `.view_api()` method. For the Whisper Space, we see the following:
+
+```
+Client.predict() Usage Info
+---------------------------
+Named API endpoints: 1
+
+ - predict(input_audio, api_name="/predict") -> value_0
+    Parameters:
+     - [Audio] input_audio: str (filepath or URL)
+    Returns:
+     - [Textbox] value_0: str (value)
+```
+
+This shows us that we have 1 API endpoint in this space, and shows us how to use the API endpoint to make a prediction: we should call the `.predict()` method, providing a parameter `input_audio` of type `str`, which is a `filepath or URL`. 
+
+We should also provide the `api_name='/predict'` argument. Although this isn't necessary if a Gradio app has a single named endpoint, it does allow us to call different endpoints in a single app if they are available. If an app has unnamed API endpoints, these can also be displayed by running `.view_api(all_endpoints=True)`.
+
+
+### Making a prediction
+
+The simplest way to make a prediction is simply to call the `.predict()` function with the appropriate arguments:
+
+```python
+from gradio_client import Client
+
+client = Client("abidlabs/en2fr")
+client.predict("Hello")
+
+>> Bonjour
+```
+
+If there are multiple parameters, then you should pass them as separate arguments to `.predict()`, like this:
+
+
+```python
+from gradio_client import Client
+
+client = Client("gradio/calculator")
+client.predict(4, "add", 5)
+
+>> 9.0
+```
+
+For certain inputs, such as images, you should pass in the filepath or URL to the file. Likewise, for the corresponding output types, you will get a filepath or URL returned. 
+
+```python
+from gradio_client import Client
+
+client = Client("abidlabs/whisper")
+client.predict("https://audio-samples.github.io/samples/mp3/blizzard_unconditional/sample-0.mp3")
+
+>> "My thought I have nobody by a beauty and will as you poured. Mr. Rochester is serve in that so don't find simpus, and devoted abode, to at might in a r—"
+```
+

+"""
+A NumPy sub-namespace that conforms to the Python array API standard.
+
+This submodule accompanies NEP 47, which proposes its inclusion in NumPy. It
+is still considered experimental, and will issue a warning when imported.
+
+This is a proof-of-concept namespace that wraps the corresponding NumPy
+functions to give a conforming implementation of the Python array API standard
+(https://data-apis.github.io/array-api/latest/). The standard is currently in
+an RFC phase and comments on it are both welcome and encouraged. Comments
+should be made either at https://github.com/data-apis/array-api or at
+https://github.com/data-apis/consortium-feedback/discussions.
+
+NumPy already follows the proposed spec for the most part, so this module
+serves mostly as a thin wrapper around it. However, NumPy also implements a
+lot of behavior that is not included in the spec, so this serves as a
+restricted subset of the API. Only those functions that are part of the spec
+are included in this namespace, and all functions are given with the exact
+signature given in the spec, including the use of position-only arguments, and
+omitting any extra keyword arguments implemented by NumPy but not part of the
+spec. The behavior of some functions is also modified from the NumPy behavior
+to conform to the standard. Note that the underlying array object itself is
+wrapped in a wrapper Array() class, but is otherwise unchanged. This submodule
+is implemented in pure Python with no C extensions.
+
+The array API spec is designed as a "minimal API subset" and explicitly allows
+libraries to include behaviors not specified by it. But users of this module
+that intend to write portable code should be aware that only those behaviors
+that are listed in the spec are guaranteed to be implemented across libraries.
+Consequently, the NumPy implementation was chosen to be both conforming and
+minimal, so that users can use this implementation of the array API namespace
+and be sure that behaviors that it defines will be available in conforming
+namespaces from other libraries.
+
+A few notes about the current state of this submodule:
+
+- There is a test suite that tests modules against the array API standard at
+  https://github.com/data-apis/array-api-tests. The test suite is still a work
+  in progress, but the existing tests pass on this module, with a few
+  exceptions:
+
+  - DLPack support (see https://github.com/data-apis/array-api/pull/106) is
+    not included here, as it requires a full implementation in NumPy proper
+    first.
+
+  The test suite is not yet complete, and even the tests that exist are not
+  guaranteed to give a comprehensive coverage of the spec. Therefore, when
+  reviewing and using this submodule, you should refer to the standard
+  documents themselves. There are some tests in numpy.array_api.tests, but
+  they primarily focus on things that are not tested by the official array API
+  test suite.
+
+- There is a custom array object, numpy.array_api.Array, which is returned by
+  all functions in this module. All functions in the array API namespace
+  implicitly assume that they will only receive this object as input. The only
+  way to create instances of this object is to use one of the array creation
+  functions. It does not have a public constructor on the object itself. The
+  object is a small wrapper class around numpy.ndarray. The main purpose of it
+  is to restrict the namespace of the array object to only those dtypes and
+  only those methods that are required by the spec, as well as to limit/change
+  certain behavior that differs in the spec. In particular:
+
+  - The array API namespace does not have scalar objects, only 0-D arrays.
+    Operations on Array that would create a scalar in NumPy create a 0-D
+    array.
+
+  - Indexing: Only a subset of indices supported by NumPy are required by the
+    spec. The Array object restricts indexing to only allow those types of
+    indices that are required by the spec. See the docstring of the
+    numpy.array_api.Array._validate_indices helper function for more
+    information.
+
+  - Type promotion: Some type promotion rules are different in the spec. In
+    particular, the spec does not have any value-based casting. The spec also
+    does not require cross-kind casting, like integer -> floating-point. Only
+    those promotions that are explicitly required by the array API
+    specification are allowed in this module. See NEP 47 for more info.
+
+  - Functions do not automatically call asarray() on their input, and will not
+    work if the input type is not Array. The exception is array creation
+    functions, and Python operators on the Array object, which accept Python
+    scalars of the same type as the array dtype.
+
+- All functions include type annotations, corresponding to those given in the
+  spec (see _typing.py for definitions of some custom types). These do not
+  currently fully pass mypy due to some limitations in mypy.
+
+- Dtype objects are just the NumPy dtype objects, e.g., float64 =
+  np.dtype('float64'). The spec does not require any behavior on these dtype
+  objects other than that they be accessible by name and be comparable by
+  equality, but it was considered too much extra complexity to create custom
+  objects to represent dtypes.
+
+- All places where the implementations in this submodule are known to deviate
+  from their corresponding functions in NumPy are marked with "# Note:"
+  comments.
+
+Still TODO in this module are:
+
+- DLPack support for numpy.ndarray is still in progress. See
+  https://github.com/numpy/numpy/pull/19083.
+
+- The copy=False keyword argument to asarray() is not yet implemented. This
+  requires support in numpy.asarray() first.
+
+- Some functions are not yet fully tested in the array API test suite, and may
+  require updates that are not yet known until the tests are written.
+
+- The spec is still in an RFC phase and may still have minor updates, which
+  will need to be reflected here.
+
+- Complex number support in array API spec is planned but not yet finalized,
+  as are the fft extension and certain linear algebra functions such as eig
+  that require complex dtypes.
