[Doc] Update CUDA and cuDNN installation (#20035) 
(1) Add CUDA and cuDNN installation section to ORT installation.
(2) For build, TRT EP refers to CUDA EP for CUDA/cuDNN installation to avoid duplication.
(3) Add comments about CUDA/cuDNN compatiblility

# Install ONNX Runtime (ORT)
See the [installation matrix](https://onnxruntime.ai) for recommended instructions for desired combinations of target
operating system, hardware, accelerator, and language.
Details on OS versions, compilers, language versions, dependent libraries, etc can be found
under [Compatibility](../reference/compatibility).
## Contents
{: .no_toc }
* TOC placeholder
{:toc}
## Requirements
* All builds require the English language package with `en_US.UTF-8` locale. On Linux,
install [language-pack-en package](https://packages.ubuntu.com/search?keywords=language-pack-en)
by running `locale-gen en_US.UTF-8` and `update-locale LANG=en_US.UTF-8`
* Windows builds
require [Visual C++ 2019 runtime](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads).
The latest version is recommended.
### CUDA and CuDNN
For ONNX Runtime GPU package, it is required to install [CUDA](https://developer.nvidia.com/cuda-toolkit) and [cuDNN](https://developer.nvidia.com/cudnn). Check [CUDA execution provider requirements](../execution-providers/CUDA-ExecutionProvider.md#requirements) for compatible version of CUDA and cuDNN.
* cuDNN 8.x requires ZLib. Follow the [cuDNN 8.9 installation guide](https://docs.nvidia.com/deeplearning/cudnn/archives/cudnn-890/install-guide/index.html) to install zlib in Linux or Windows. Note that the official gpu package does not support cuDNN 9.x.
* The path of CUDA bin directory must be added to the PATH environment variable.
* In Windows, the path of cuDNN bin directory must be added to the PATH environment variable.
## Python Installs
### Install ONNX Runtime (ORT)
#### Install ONNX Runtime CPU
```bash
pip install onnxruntime
```
#### Install ONNX Runtime GPU (CUDA 11.x)
The default CUDA version for ORT is 11.8.
```bash
pip install onnxruntime-gpu
```
#### Install ONNX Runtime GPU (CUDA 12.x)
For Cuda 12.x, please use the following instructions to install from [ORT Azure Devops Feed](https://aiinfra.visualstudio.com/PublicPackages/_artifacts/feed/onnxruntime-cuda-12/PyPI/onnxruntime-gpu/overview)
```bash
pip install onnxruntime-gpu --extra-index-url https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/onnxruntime-cuda-12/pypi/simple/
```
### Install ONNX to export the model
```bash
## ONNX is built into PyTorch
pip install torch
```
```bash
## tensorflow
pip install tf2onnx
```
```bash
## sklearn
pip install skl2onnx
```
## C#/C/C++/WinML Installs
### Install ONNX Runtime (ORT)
#### Install ONNX Runtime CPU
```bash
# CPU
dotnet add package Microsoft.ML.OnnxRuntime
```
#### Install ONNX Runtime GPU (CUDA 11.x)
The default CUDA version for ORT is 11.8
```bash
# GPU
dotnet add package Microsoft.ML.OnnxRuntime.Gpu
```
#### Install ONNX Runtime GPU (CUDA 12.x)
1. Project Setup
Ensure you have installed the latest version of the Azure Artifacts keyring from the
its [Github Repo](https://github.com/microsoft/artifacts-credprovider#azure-artifacts-credential-provider). <br> Add
a nuget.config file to your project in the same directory as your .csproj file.
```xml
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<clear/>
<add key="onnxruntime-cuda-12"
value="https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/onnxruntime-cuda-12/nuget/v3/index.json"/>
</packageSources>
</configuration>
```
2. Restore packages
Restore packages (using the interactive flag, which allows dotnet to prompt you for credentials)
```bash
dotnet add package Microsoft.ML.OnnxRuntime.Gpu
```
Note: You don't need --interactive every time. dotnet will prompt you to add --interactive if it needs updated
credentials.
#### DirectML
```bash
dotnet add package Microsoft.ML.OnnxRuntime.DirectML
```
#### WinML
```bash
dotnet add package Microsoft.AI.MachineLearning
```
## Install on web and mobile
Unless stated otherwise, the installation instructions in this section refer to pre-built packages that include support
for selected operators and ONNX opset versions based on the requirements of popular models. These packages may be
referred to as "mobile packages". If you use mobile packages, your model must only use the
supported [opsets and operators](../reference/operators/mobile_package_op_type_support_1.14.md).
Another type of pre-built package has full support for all ONNX opsets and operators, at the cost of larger binary size.
These packages are referred to as "full packages".
If the pre-built mobile package supports your model/s but is too large, you can create
a [custom build](../build/custom.md). A custom build can include just the opsets and operators in your model/s to reduce
the size.
If the pre-built mobile package does not include the opsets or operators in your model/s, you can either use the full
package if available, or create a custom build.
### JavaScript Installs
#### Install ONNX Runtime Web (browsers)
```bash
# install latest release version
npm install onnxruntime-web
# install nightly build dev version
npm install onnxruntime-web@dev
```
#### Install ONNX Runtime Node.js binding (Node.js)
```bash
# install latest release version
npm install onnxruntime-node
```
#### Install ONNX Runtime for React Native
```bash
# install latest release version
npm install onnxruntime-react-native
```
### Install on iOS
In your CocoaPods `Podfile`, add the `onnxruntime-c`, `onnxruntime-mobile-c`, `onnxruntime-objc`,
or `onnxruntime-mobile-objc` pod, depending on whether you want to use a full or mobile package and which API you want
to use.
#### C/C++
```ruby
use_frameworks!
# choose one of the two below:
pod 'onnxruntime-c' # full package
#pod 'onnxruntime-mobile-c' # mobile package
```
#### Objective-C
```ruby
use_frameworks!
# choose one of the two below:
pod 'onnxruntime-objc' # full package
#pod 'onnxruntime-mobile-objc' # mobile package
```
Run `pod install`.
#### Custom build
Refer to the instructions for creating a [custom iOS package](../build/custom.md#ios).
### Install on Android
#### Java/Kotlin
In your Android Studio Project, make the following changes to:
1. build.gradle (Project):
```gradle
repositories {
mavenCentral()
}
```
2. build.gradle (Module):
```gradle
dependencies {
// choose one of the two below:
implementation 'com.microsoft.onnxruntime:onnxruntime-android:latest.release' // full package
//implementation 'com.microsoft.onnxruntime:onnxruntime-mobile:latest.release' // mobile package
}
```
#### C/C++
Download the [onnxruntime-android](https://mvnrepository.com/artifact/com.microsoft.onnxruntime/onnxruntime-android) (
full package) or [onnxruntime-mobile](https://mvnrepository.com/artifact/com.microsoft.onnxruntime/onnxruntime-mobile) (
mobile package) AAR hosted at MavenCentral, change the file extension from `.aar` to `.zip`, and unzip it. Include the
header files from the `headers` folder, and the relevant `libonnxruntime.so` dynamic library from the `jni` folder in
your NDK project.
#### Custom build
Refer to the instructions for creating a [custom Android package](../build/custom.md#android).
## Install for On-Device Training
Unless stated otherwise, the installation instructions in this section refer to pre-built packages designed to perform
on-device training.
If the pre-built training package supports your model but is too large, you can create
a [custom training build](../build/custom.md).
### Offline Phase - Prepare for Training
```bash
python -m pip install cerberus flatbuffers h5py numpy>=1.16.6 onnx packaging protobuf sympy setuptools>=41.4.0
pip install -i https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/ORT/pypi/simple/ onnxruntime-training-cpu

```bash
pip install torch-ort
python -m torch_ort.configure
```
**Note**: This installs the default version of the `torch-ort` and `onnxruntime-training` packages that are mapped to
specific versions of the CUDA libraries. Refer to the install options in [onnxruntime.ai](https://onnxruntime.ai).
