ImportError: DLL load failed: The specified module could not be found

(Lou Spironello) #1

I went back to work on the first lesson and now I’m getting errors with PILL(pillow).
I seem to be getting this error in a number of other notebooks as well. Things were working yesterday and I can’t remember what I changed. I uninstalled pillow and reinstalled. That didn’t seem to work.

Ideas? Thank you.

Instead of using conda to uninstall and reinstall I used pip and that seemed to fix the problem.


Use Pillow from conda-forge:

conda install -c conda-forge Pillow

I’ve had this problem on multiple computers and Python installations and environments, especially if some of the components are from conda-forge but Pillow isn’t, and switching to the conda-forge version of Pillow always works like a charm!

Hi @xjdeng @lspironello

I’m facing the below issue can you give me any suggestions what to do?

I have tried conda install -c defaults intel-openmp -f but it doesn’t work.
