Installation on Windows via Conda¶
Anacondais a free and open source distribution of Python and R for computational science. Anaconda is dedicated to simplifying package management and deployment. Anaconda’s packages are managed using the package management system Conda. Conda is an open source package management system and environment management system that runs on Windows, macOS, and Linux.
Environmental preparation¶
Before performing PaddlePaddle installation, please make sure that your Anaconda software environment is properly installed. For software download and installation, see Anaconda’s official website (https://www.anaconda.com/). If you have installed Anaconda correctly, follow these steps to install PaddlePaddle.
1.1 Create Virtual Environment¶
1.1.1 Create the Anaconda Virtual Environment¶
Create virtual environment First create the Anaconda virtual environment according to the specific Python version. The Anaconda installation of PaddlePaddle supports the following four Python installation environments.
If you want to use python version 2.7:
conda create -n paddle_env python=2.7
If you want to use python version 3.5:
conda create -n paddle_env python=3.5
If you want to use python version 3.6:
conda create -n paddle_env python=3.6
If you want to use python version 3.7:
conda create -n paddle_env python=3.7
If you want to use python version 3.8:
conda create -n paddle_env python=3.8
1.1.2 Enter the Anaconda Virtual Environment¶
for Windows
activate paddle_env
for MacOS/Linux
conda activate paddle_env
1.2 Confirm Other Environments¶
Confirm that your conda virtual environment and the Python loaction which is preapared to install PaddlePaddle are where you expected them for your computer may have multiple Pythons environments. Enter Anaconda’s command line terminal and enter the following command to confirm the Python location.
1.2.1 If you are using Python 2, use the following command to get the Python path. Depending on your environment, you may need to replace python in all command lines in the instructions with specific Python path.
In a Windows environment, the command to get the Python path is:
where python
In a MacOS/Linux environment, the command to get the Python path is:
which python
If you are using Python 3, use the following command to get the Python path. Depending on your environment, you may need to replace python in all command lines in the instructions with specific Python path.
In a Windows environment, the command to get the Python path is:
where python3
In a MacOS/Linux environment, the command to get the Python path is:
which python3
1.2.2 Check the version of Python
If you are using Python 2, use the following command to confirm it’s version is 2.7.15+
python --version
If you are using Python 3, use the following command to confirm it’s version is 3.5.1+/3.6/3.7/3.8
python3 --version
1.2.3 Confirm that Python and pip are 64bit, and the processor architecture is x86_64 (or x64, Intel 64, AMD64) architecture. Currently PaddlePaddle does not support arm64 architecture. The first line below print “64bit”, the second line prints “x86_64 (or x64, AMD64).”
If you are using Python2:
python -c "import platform;print(platform.architecture()[0]);print(platform.machine())"
If you are using Python3:
python3 -c "import platform;print(platform.architecture()[0]);print(platform.machine())"
INSTALLATION¶
We will introduce conda installation here.
Choose CPU/GPU¶
If your computer doesn’t have NVIDIA® GPU, please install the CPU Version of PaddlePaddle
If your computer has NVIDIA® GPU, please make sure that the following conditions are met and install the GPU Version of PaddlePaddle
Installation Step¶
You can choose the following version of PaddlePaddle to start installation:
2.1 CPU Version of PaddlePaddle¶
conda install paddlepaddle
2.2 GPU Version of PaddlePaddle¶
CUDA9.0 PaddlePaddle
conda install paddlepaddle-gpu==1.8.5 cudatoolkit=9.0 -c paddle
CUDA10.0 PaddlePaddle
conda install paddlepaddle-gpu==1.8.5 cudatoolkit=10.0 -c paddle
Verify installation¶
After the installation is complete, you can use python
or python3
to enter the Python interpreter and then use import paddle.fluid
and fluid.install_check.run_check()
If Your Paddle Fluid is installed succesfully!
appears, to verify that the installation was successful.
Notice¶
For domestic users who cannot connect to the Anaconda official source, you can add Tsinghua source to install it according to the following command.
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/
conda config --set show_channel_urls yes
