Manage Modules in Your Python Virtual Environment
Users can manage their own python environment (including installing needed modules) using virtual environments (works with python2 and python3). Please see the documentation on virtual environments on python.org for details.
Create Virtual Environment
Users can create as many virtual environments, each in their own directory, as needed.
- python2:
python -m virtualenv <your virtual environment directory>
- python3:
python3 -m venv <your virtual environment directory>
Activate Virtual Environment
Next you need to activate a virtual environment before using it:
source <your virtual environment directory>/bin/activate
Install Python Modules Using pip
After activating your virtual environment, you can now install python modules for the activated environment:
- NOTE: It's always a good idea to update
pip
first:
pip install --upgrade pip
- Install the module:
pip install <module name>
- List installed python modules in the environment:
pip list modules
- Example: Install
tensorflow
andkeras
like this:
$ module load python3 $ python3 -m venv tensorflow $ source tensorflow/bin/activate (tensorflow) $ pip install --upgrade pip Collecting pip Using cached https://files.pythonhosted.org/packages/30/db/9e38760b32e3e7f40cce46dd5fb107b8c73840df38f0046d8e6514e675a1/pip-19.2.3-py2.py3-none-any.whl Installing collected packages: pip Found existing installation: pip 18.1 Uninstalling pip-18.1: Successfully uninstalled pip-18.1 Successfully installed pip-19.2.3 (tensorflow) -bash-4.2$ pip install tensorflow keras Collecting tensorflow Using cached https://files.pythonhosted.org/packages/de/f0/96fb2e0412ae9692dbf400e5b04432885f677ad6241c088ccc5fe7724d69/tensorflow-1.14.0-cp36-cp36m-manylinux1_x86_64.whl : : : Successfully installed absl-py-0.8.0 astor-0.8.0 gast-0.2.2 google-pasta-0.1.7 grpcio-1.23.0 h5py-2.9.0 keras-2.2.5 keras-applications-1.0.8 keras-preprocessing-1.1.0 markdown-3.1.1 numpy-1.17.1 protobuf-3.9.1 pyyaml-5.1.2 scipy-1.3.1 six-1.12.0 tensorboard-1.14.0 tensorflow-1.14.0 tensorflow-estimator-1.14.0 termcolor-1.1.0 werkzeug-0.15.5 wheel-0.33.6 wrapt-1.11.2 (tensorflow) -bash-4.2$ pip list modules Package Version -------------------- ------- absl-py 0.8.0 astor 0.8.0 gast 0.2.2 google-pasta 0.1.7 grpcio 1.23.0 h5py 2.9.0 Keras 2.2.5 Keras-Applications 1.0.8 Keras-Preprocessing 1.1.0 Markdown 3.1.1 numpy 1.17.1 pip 19.2.3 protobuf 3.9.1 PyYAML 5.1.2 scipy 1.3.1 setuptools 40.6.2 six 1.12.0 tensorboard 1.14.0 tensorflow 1.14.0 tensorflow-estimator 1.14.0 termcolor 1.1.0 Werkzeug 0.15.5 wheel 0.33.6 wrapt 1.11.2
