$sudo pip install virtualenv
Create a virtual environment (recommended)
Create a new virtual environment by choosing a Python interpreter and making a ./venv directory to hold it:
$ virtualenv --system-site-packages -p python3 ./venv
Activate the virtual environment using a shell-specific command:
$ source ./venv/bin/activate # sh, bash, ksh, or zsh
When virtualenv is active, your shell prompt is prefixed with (venv).
Install packages within a virtual environment without affecting the host system setup. Start by upgrading pip:
$ pip install --upgrade pip$ pip list # show packages installed within the virtual environment
And to exit virtualenv later:
deactivate # don't exit until you're done using TensorFlow pycharm使用搭建好的环境
