hamid-hassani commented 6 years ago

Description:

When I run my example file include this codes: from NuGridPy import mesa as ms

What I've get:

Traceback (most recent call last): File "py.py", line 1, in from NuGridPy import mesa as ms ImportError: No module named NuGridPy

Can anyone help me with this?

Any help?

pfmoore commented 6 years ago

It sounds like you don't have NuGridPy installed. That's not a pip issue, you use pip to install NuGridPy - pip install NuGridPy.

I have installed this package many times, My results after : 

pip install NuGridPy

Hey @theparmis!

What is the output of python --version and pip --version?

hamid-hassani commented 6 years ago

Hey there! Python 2.7.9 :: Anaconda custom (64-bit) pip 10.0.1 from /Users/myuser/anaconda2/lib/python2.7/site-packages/pip (python 2.7)

hamid-hassani commented 6 years ago

Any Help?!!

pradyunsg commented 6 years ago

Hey @theparmis!

You need to import from nugridpy. The capitalization matters.

from nugridpy import mesa as ms

I'd suggest you file an issue over at NuGridPy about their incorrect example in the README. :)

I've gone ahead and done that -- https://github.com/NuGrid/NuGridPy/issues/55.

It is not possible that such ridiculous error wasted my time for a month!

Thank you!

After that I get this error:

Hehe. You're welcome. :)

After that I get this error:

The right place for asking for help dealing with package-specific issues would be the project itself -- please ask on a NuGridPy forum/issue-tracker/mailing-list/whatever-they-use.

I'll go ahead and close this issue since there doesn't seem anything actionable from pip's end here. :)

fherwig commented 6 years ago

@theparmis NameError: name 'boltzmann_sigma' is not defined was an error that took a few days to note, but it is now fixed (NuGridPy failed to build for a short while, but this is fixed now). This error would not appear in the version 0.74 from PyPIP, only if you installed the latest version from git.
