TypeError: file must have 'read' and 'readline' attributes

[hobbyist]

Sorry, my mistake - it should work if you do this:

import glob
 
def open_train_data():
    return glob.glob('/home/mojito/Desktop/CNN/datasets/training_data/images/*') #the '*' is a 'wildcard' and it means to match one or more characters
  
for f in open_train_data():
   dict1 = pickle.load(open(f, 'rb'))
   ###do whatever else you need to

I forgot to open the file.

I am getting this error:

Using TensorFlow backend.
Traceback (most recent call last):
  File "source_code_modified.py", line 80, in <module>
    dict1 = pickle.load(open(f, 'rb'))
_pickle.UnpicklingError: A load persistent id instruction was encountered,
but no persistent_load function was specified.

I am trying to solve it though, but I thought posting it for more help. Thank you...
