The ‘data’ object was created by an older version of PyG. If this error occurred while loading

This problem occurs in the pytorch environment

reason

 The torch-geometric version does not match the torch version,

Because the normal installation torch-geometric tutorial is: pip install torch-geometric The version installed in this way is version 2.0.X , and the version is not compatible.

 For torch-geometric version 2.0.X, the error described above will occur when reading the data at this time. At this time, we need to download the torch-geometric version lower than 1.XX.

solution

Uninstall the original version first

Type in terminal

pip uninstall torch-geometric

Download version 1.XX again

After installing torch-geometric==1.6.0 version, the above error will not be reported

Type in terminal

pip install torch-geometric==1.6.0

problem solved
