No module named 'castle' after installed the gcastle == 1.0.3rc2

[matthewmeng]

Hi I already installed gcastle with pip install gcastle==1.0.3rc2.
But when I try to run the demo program like anm_demo.py.
There still an error said
from castle.common import GraphDAG ModuleNotFoundError: No module named 'castle'

Anyone know why there is a ModuleNotFoundError even I have installed the package already?

It could be that you have multiple python environments/versions available on your system and installed gCastle on another one. You can try to run python -m pip gcastle==1.0.3rc2 and see if it works.

There are some more helpful tips here that you can try if the above does not work out: https://stackoverflow.com/questions/40834656/installed-module-using-pip-not-found.

Thanks, I've tried the python -m pip gcastle==1.0.3rc2 but still didn't work.
will try the virtual env to see if it will work

Make sure that the python you use to run the code is the same as the one you installed with. It's very easy to get confused if there are multiple versions. If you use something like PyCharm you should be able to install the package directly in the interpreter settings (or change which python interpreter is used to run with).
