INFO: pip is looking at multiple versions of <Python from Requires-Python> to determine which version is compatible with other requirements. This could take a while.
INFO: pip is looking at multiple versions of spacy to determine which version is compatible with other requirements. This could take a while.

The conflict is caused by:
    spacy 3.5.3 depends on thinc<8.2.0 and >=8.1.8
    kgtk 1.5.3 depends on thinc==7.4.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
