[question] use anaconda/pip libraries in RPS #105

Open amastrobera opened 4 years ago

amastrobera commented 4 years ago

Does RPS runs only on IronPython or is it possible to include (CPython) libraries from Anaconda / PIP ? I believe only Python2 is allowed.

I tried to tweak the Configuration --> Search Path and add my C:\Users\angelo\Anaconda2\Lib\site-packages but I get errors when trying to use it.

What are the exact errors you get?

Pure python libraries should not be a problem - adding libraries that include native code (*.pyd) or similar is much more tricky.

Your best bet is probably to shell out (subprocess module) to a CPython script and handle input / output...

amastrobera commented 4 years ago

on the windows command prompt it's all clean

conda install -c conda-forge numpy
python -c "import numpy" # no error

on the RPS

IronPython 2.7.7 (2.7.7.0) on .NET 4.0.30319.42000 (64-bit)

ImportError: 
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

Original error was: cannot import multiarray from numpy.core

Yes, I have used subprocess before. I think we can do better if we manage to import some python2 libraries

so here's the thing. numpy is one of those libraries that aren't pure python. This link here might help you, but it looks a bit like a rabbit hole: https://stackoverflow.com/questions/29397540/how-to-install-numpy-and-scipy-for-ironpython27-old-method-doesnt-work

@amastrobera I guess you would find answer at pyRevit repo: https://github.com/eirannejad/pyRevit because @eirannejad managed to create CPython engine to run inside .NET environment. I haven't digged into where he wrote it, but you might ask him.

amastrobera commented 4 years ago

@daren-thomas I am trying that. thanks for the link.

Installing this ironpkg, gives an error ...

@daren-thomas

... but I had better luck with this old post. I run the script from Tess on these eggs of numpy and scipy.

I now have the IronPython version of Numpy and Scipy. What should I change in Environment Variables / Revit Configuration / etc to be able to import numpy ? I still get this error

Question for later.

Now, what happens if I want to import a library that uses numpy, but it's not in IronPython, such as osgeo ? Such a library will automatically look for the CPython/other version of numpy, unless I add IronPython2.7/Lib/site-package in the PYTHONPATH, but this may be misleading ...

... and anyway,
