[ryunosuke0723]

I was trying to load myo64.dill to connect python to myo armband.
But, the error happend.
「cannot load library 'C:\path\to\myo-sdk\bin\myo64.dll': error 0x7e. Additionally, ctypes.util.find_library() did not manage to locate a library called 'C:\\path\\to\\myo-sdk\\bin\myo64.dll'」
Does someone know how can I fix this?　please.

Does the file C:\path\to\myo-sdk\bin\myo64.dll actually exist?

I have the same issue.

Is there somewhere where we can manually download the dll file? I don't see it in the SDK.

My solution was to use Python 3.7.4.
I tried using python 3.11 and got these sorts of errors.
