ModuleNotFoundError: No module named 'igl.pyigl'

[JonathanPham]

Hi,

I installed the source code via python setup.py install. But, when I ran import igl in Python, I got the error ModuleNotFoundError: No module named 'igl.pyigl'. It seems like the issue is coming from the command, from .pyigl import *, in libigl-python-bindings/igl/__init__.py.

Any recommendations on how to resolve this? Am I importing igl incorrectly in Python?

Thanks!

Also met the same error. Installing in a conda environment within a nivdia docker via python setup.py install.

I resolved this error by:

$ git clone https://github.com/libigl/libigl-python-bindings.git
$ cd libigl-python-bindings
$ conda activate igl # with python, pip, numpy and scipy installed in this env
$ python setup.py install # if this step success, you should get a new directory named build
$ export CONDA_HOME=/data/miniconda3 # specify your conda home directory
$ cp -r ./build/lib.linux-x86_64-3.8/igl ${CONDA_HOME}/envs/igl/lib/python3.8/site-packages/

Now you should be able to import igl with no error. However, I don't know why this works and wonder if anyone can provide more elegant solutions, thanks.

@teseoch Hi, would you please consider to release v2.2.2 version of conda libigl package? I'm working on a 2D bbw project, and have to install libigl via python setup.py install since the current v2.2.1 conda package had not fixed the 2D bbw assertion bug reported in #90. However, compiling libigl from scratch is error-prone as commented above. I'd appreciate if you could release a new conda version, which I believe will save my day and others who need 2D bbw.

I have also run into this error (whether I use a conda install or try and install from the source code). Unfortunately, the solution proposed above doesn't work for me, even though I am also working on a linux system. Any suggestions?

Also running into trouble with this currently - installed through conda, python 3.8.

I don't know why but the libraries were not copied after in the imported igl directory after I did python setup.py install. To fix that issue, I had to manually copy them. In my case:

cp build/lib.macosx-11.1-arm64-3.9/igl/*.so igl

hi, have you solve this problem?

hi, have you solve this problem?

In my case yes, but of course the lib directory can change depending of the architecture.

I'm hoping this problem may have been solved with the migration to pip (pip install libigl). If this is still an issue, please reopen.

Thanks. Copying the compiled files to site-packages solved my issue.
