Pip throws an error after loading the machine learning modules. How can I fix it?


Machine learning modules (tensorflow, pytorch, opencv etc.) include a version of pip that is newer than the one installed with Anaconda. As a result it will throw an error when you try to use it.

$ pip --version
Traceback (most recent call last):
  File "/apps/cent7/anaconda/5.1.0-py36/bin/pip", line 7, in <module>
    from pip import main
ImportError: cannot import name 'main'

The preferred way to use pip with the machine learning modules is to invoke it via Python as shown below.

$ python -m pip --version
