4. PaddlePaddle's support for GPU:
==================================
* Currently, **PaddlePaddle** only supports **CUDA** driver of **NVIDIA** graphics card.
* You need to install `cuDNN `_ , and version 7.6+ is required(For CUDA9/10)
* If you need GPU multi-card mode, you need to install `NCCL 2 `_
* Only Ubuntu/CentOS support NCCL 2
* You need to install `CUDA `_ , depending on your system, there are different requirements for CUDA version:
* Windows install GPU version
* Windows 7 / 8 / 10 support CUDA 9.0 / 10.0 single-card mode, but don't support CUDA 9.1/9.2/10.1
* don't support install using **nvidia-docker**
* Ubuntu install GPU version
* Ubuntu 14.04 supports CUDA 10.0/10.1, but doesn't support CUDA 9.0/9.1/9.2

* CentOS 6 supports CUDA 9.0/9.1/9.2/10.0/10.1 single-card mode
* If you compile and install using native source code:
* CentOS 7 supports CUDA 9.0/9.1/9.2/10.0/10.1, CUDA 9.1 supports single-card mode only
* CentOS 6 is not recommended, we don't provide official support in case of compilation problems
* If you install using **nvidia-docker** , CentOS 7 supports CUDA 9.0/9.1/9.2/10.0/10.1
* MacOS isn't supported: PaddlePaddle has no GPU support in Mac OS platform
Please make sure your environment meets the above conditions. If you have other requirements, please refer to `Appendix `_ .

* Support for MacOS
* not support NCCL
The first way to install: use pip to install
============================================
You can choose any of the four ways to install: "use pip to install", "use Conda to install", "use Docker to install", "compiling from the source code"
This section describes how to use pip to install.
1. You need to confirm that your operating system meets the requirements listed above
2. You need to confirm that your processor meets the requirements listed above
3. Confirm that the Python where you need to install PaddlePaddle is your expected location, because your computer may have multiple Python
If you are using Python 2, use the following command to output Python path. Depending on your environment, you may need to replace Python in all command lines in the description with specific Python path
In the Windows environment, the command to output Python path is:
::
where python
In the MacOS/Linux environment, the command to output Python path is:
::
which python
If you are using Python 3, use the following command to output Python path. Depending on your environment, you may need to replace Python in all command lines in the description with specific Python path
In the Windows environment, the command to output Python path is:
::
where python3
In the MacOS/Linux environment, the command to output Python path is:
::
which python3
4. Check the version of Python
If you are using Python 2，confirm it is 2.7.15+ using command
::
python --version
If you are using Python 3，confirm it is 3.5.1+/3.6/3.7 using command
::
python3 --version
5. Check the version of pip and confirm it is 9.0.1+
If you are using Python 2
::
python -m ensurepip
python -m pip --version
If you are using Python 3
::
python3 -m ensurepip
python3 -m pip --version
6. Confirm that Python and pip is 64 bit，and the processor architecture is x86_64(or called x64、Intel 64、AMD64)architecture. Currently, PaddlePaddle doesn't support arm64 architecture. The first line below outputs "64bit", and the second line outputs "x86_64", "x64" or "AMD64" :
If you use Python 2
::
python -c "import platform;print(platform.architecture()[0]);print(platform.machine())"
If you use Python 3
::
python3 -c "import platform;print(platform.architecture()[0]);print(platform.machine())"
7. If you want to use `pip `_ to install PaddlePaddle, you can use the command below directly:
(1). **CPU version** : If you only want to install CPU version, please refer to command below
If you are using Python 2, command to install CPU version is:
::
python -m pip install paddlepaddle==2.0.0b0 -i https://mirror.baidu.com/pypi/simple
or
python -m pip install paddlepaddle==2.0.0b0 -i https://pypi.tuna.tsinghua.edu.cn/simple
If you are using Windows environment, please use the following instruction:
python -m pip install paddlepaddle==2.0.0b0 -f https://paddlepaddle.org.cn/whl/stable.html
If you are using Python 3, please change **python** in the above command to **python3** and install.
(2). **GPU version** : If you only want to install GPU version, please refer to command below
Note:
* You need to confirm that your GPU meets the requirements listed above
If you are using Python2, please attention that PaddlePaddle installed through command below only supports CUDA10.0 under Windows、Ubuntu、CentOS:
::
python -m pip install paddlepaddle-gpu==2.0.0b0 -i https://mirror.baidu.com/pypi/simple
or
python -m pip install paddlepaddle-gpu==2.0.0b0 -i https://pypi.tuna.tsinghua.edu.cn/simple
If you are using Windows environment, please use the following instruction:
python -m pip install paddlepaddle_gpu==2.0.0b0 -f https://paddlepaddle.org.cn/whl/stable.html
If you are using Python 3, please change **python** in the above command to **python3** and install.
8. Verify installation
After the installation is complete, you can use `python` or `python3` to enter the Python interpreter and then use `import paddle.fluid as fluid` and then `fluid.install_check.run_check()` to verify that the installation was successful.
If `Your Paddle Fluid is installed succesfully!` appears, it means the installation was successful.
9. For more information to help, please refer to:
`install under Ubuntu `_
`install under CentOS `_
`install under MacOS `_
`install under Windows `_
The second way to install: compile and install with source code
===============================================================
- If you use PaddlePaddle only, we suggest you installation methods **pip** to install.
- If you need to develop PaddlePaddle, please refer to `compile from source code `_
