TypeError: a bytes-like object is required, not 'str' while loading with pickle

问题

I'm using Python 3.6 and Spyder (Anaconda). I have tried many things but nothing worked out. I don't know why this error is coming always to me while loading with pickle.

filename = "allfeatures.txt"
allfeatures = open(filename, 'r').read()
with open(filename) as f:
     allfeatures = list(f)
allconcat = np.vstack(list(allfeatures.values()))

TypeError                           Traceback (most recent call last)
 AttributeError: 'list' object has no attribute 'values'

回答1:

You need to open your file as a binary file:

pickle.loads(open("accounts.txt", 'rb').read())

Otherwise, it's using an str to read the data.
