TypeError: 'module' object is not callable

While attempting to install (or upgrade) the ParaMonte::Python library via pip or pip3,

pip install --user --upgrade paramonte

one may get an error like the following,

Traceback (most recent call last):
  File "/opt/apps/intel18/python3/3.7.0/bin/pip", line 11, in <module>
    sys.exit(main())
TypeError: 'module' object is not callable

Apparently, this error happens because of a conflict between the user-specific and the global installations of pip. If you encounter such an error, a quick resolution might be the following command,

python3 -m pip uninstall pip
