OSError: cannot load library 'sndfile.dll': error 0x7e - Windows 10 x64 #13
Closed
Description
Using new pysoundfile version 0.10.3.post1, I cannot load conda librosa 0.8.0 on a Win10 x64 machine. The sndfile.dll library cannot be found, even though it installs to the correct place ('C:\Users\me\Miniconda3\envs\py37\Library\bin\sndfile.dll'), perhaps due to the fact that ctypes.util.find_library reports the above location without the "C:" at the start (noticed by @mgeier).
The issue has been discussed extensively here. The same issue occurs in a conda Python 3.8 environment into which pip librosa + dependencies had been previously installed, and then removed.
Here is the dump after trying to import librosa using
import librosa as lr
