Error when installing d2l: module pkgutil has no attribute ImpImporter.

[hamiddashti]

I am trying to install the d2l library using the pip install d2l==1.0.3 and I get the following error:

AttributeError: module pkgutil has no attribute ImpImporter. Did you mean: zipimporter note: This error originates from a subprocess, and is likely not a problem with pip.

How can I solve this? I have my conda env setup properly.

Thanks!

I am running into this problem also. It is a conflict between python 3.12 and numpy 1.23.5.

d2l has a hard requirement on numpy 1.23.5

Collecting numpy==1.23.5 (from d2l==1.0.3)
  Using cached numpy-1.23.5.tar.gz (10.7 MB)

numpry 1.23.5 uses ImpImporter. Python 3.12 removed support for pkgutil.ImpImporter.

I've confirmed that numpy 1.26.4 has fixed this problem, but that doesn't fix d2l's requirement for 1.23.5.

pip install -U pip wheel setuptools
python ./setup.py bdist_wheel
pip install -U ./dist/d2l-1.0.3-py3-none-any.whl

Results in a successful install using python 3.12. You may or may not have to install gfortran and libopenblas-dev depending upon your distro to get scipi to build. Numpy 1.26 required the uprev scipi.

Not tested yet to see if this doesn't break somehow in runtime.

Hat tip to @slewsys and #2608 (comment) for the pointer on how to rebuild the wheel.
