Pickle: TypeError: a bytes-like object is required, not 'str' [duplicate]

Answer 1

You need to change 'str' to 'bytes'. Try this:

class StrToBytes:
    def __init__(self, fileobj):
        self.fileobj = fileobj
    def read(self, size):
        return self.fileobj.read(size).encode()
    def readline(self, size=-1):
        return self.fileobj.readline(size).encode()

with open(fname, 'r') as f:
    obj = pickle.load(StrToBytes(f))
