No module named 'lie_learn.representations.SO3.irrep_bases'

[Syhzs]

I failed import this .c file . I have a c compile(vs c++ 2015) and already pip install cython.( python 3.6 ,pytorch 1.1.0 cuda 9.0)

I also ran into this error

Same error here: ModuleNotFoundError: No module named 'lie_learn.representations.SO3.irrep_bases'

You might want to try:

pip install git+https://github.com/AMLab-Amsterdam/lie_learn

for me this did not work either and was running into a cython issue but installing an older commit worked:

pip install git+https://github.com/AMLab-Amsterdam/lie_learn@6d02c2a1705a05340a128cb8d86c19076d0f5f46

@HannesStark
lie_learn cannot be installed using these two commands. My environment is anaconda with pytorch1.8 and python3.7.

probably, you need to download the whole project and use setup.py file to install using the command python setup.py install
personally, the setup.py has problem leading the Cpython report the compile error "is not a valid module name", I modified the code of setup.py in line 29 extensions = cythonize(extensions) to extensions = cythonize(files), and it works.

I have solved this problem.
at first,you should run "pip install cpython","pip install easycpython",and then go to the pakage root,"pip install . "。
then ,you enter the .\representations\SO3,and will find the irrep_bases.pyx and the irrep_bases.c。
at least ,open the cmd in this dir,run "easycpython irrep_bases.pyx"，after that,you will find a pyd file，that is over.
