Cannot open .pickle files

[mdciri]

I cannot open any .pickle file in pretrained_features.
My current pickle version is the 4.0.

execuiting your function collect_pretrained_features_from_folder() in explore_dataset.py(), I get:

'the requested features were not calculated.'

beacuse just doing:

curr_features_dict = pickle.load(open(all_feature_dict_filenames[0], "rb"))

I get the following error:

TypeError: _reconstruct: First argument must be a sub-type of ndarray
