I removed torch and then install torch by the following command:
pip3 install torch==1.2.0 torchvision==0.4.0 -f https://download.pytorch.org/whl/torch_stable.html

Now, I could import torch. Also, I could install matchzoo-py successfully but when I import torch and then import matchzoo, I receive this error that is related to pandas version I think:
AttributeError: module 'pandas' has no attribute 'core'

I would appreciate it if guide me.
