bob.extension.load_bob_library('bob.core', __file__) attributeerror: module 'bob.extension' has no attribute 'load_bob_library'

[Adesoji1]

using conda 4.13 on python 3.6 environment, Ubuntu wsl 20.04, when i run bob pad run-pipeline --help i get the werror below

bob.extension.load_bob_library('bob.core', file) attributeerror: module 'bob.extension' has no attribute 'load_bob_library'

How do i resolve this issue? Is there any tutorial or video lecture on how to use bob.pad to run a pipeline on a custom dataset similar to OULU_NPY dataset?
