Import Error DGL with PyTorch

Hi,

I have an error while importing DGL library. Shows a ‘.dll’ file missing, however it is available when I look in the mentioned path. Any suggestions?

System Settings
Cuda: Not available
Installation: pip install dgl
torch version: 1.8.1
numpy | scipy: 1.20.3 | 1.6.3
Python: 3.8.8

Traceback
import dgl

What’s your DGL version? Also, does the error still happen if you import DGL outside PyCharm?
