1 year ago @ramajoballester Hi, are you sure this error could occur in the dev-1.x branch? According to your error message, this error is triggered by the old networkx versions. Solve this by updating networkx>=2.5 which is required in dev-1.x branch. Some references: https://stackoverflow.com/questions/66174862/import-error-cant-import-name-gcd-from-fractions
Prerequisite
Task
I'm using the official example scripts/configs for the officially supported tasks/models/datasets.

Additional information
I am following the installation guidelines in getting_started.md.
EDIT: found a solution. The problem was caused by a faulty pytorch installation. Solved by installing with pip instead of conda. Installation and demo verification went fine. Please, delete issue.
