neuspell: Error quick-start code snippet - UnpicklingError: invalid load key, '<'.

Hello,

I tried to run the quick-start code snippet :

import neuspell
from neuspell import available_checkers, BertChecker

""" see available checkers """
print(f"available checkers: {neuspell.available_checkers()}")
# → available checkers: ['BertsclstmChecker', 'CnnlstmChecker', 'NestedlstmChecker', 'SclstmChecker', 'SclstmbertChecker', 'BertChecker', 'SclstmelmoChecker', 'ElmosclstmChecker']

""" select spell checkers & load """
checker = BertChecker()
checker.from_pretrained()

""" spell correction """
checker.correct("I luk foward to receving your reply")
# → "I look forward to receiving your reply"
checker.correct_strings(["I luk foward to receving your reply", ])
# → ["I look forward to receiving your reply"]
checker.correct_from_file(src="noisy_texts.txt")
# → "Found 450 mistakes in 322 lines, total_lines=350"

""" evaluation of models """
checker.evaluate(clean_file="bea60k.txt", corrupt_file="bea60k.noise.txt")
# → data size: 63044
# → total inference time for this data is: 998.13 secs
# → total token count: 1032061
# → confusion table: corr2corr:940937, corr2incorr:21060,
#                    incorr2corr:55889, incorr2incorr:14175
# → accuracy is 96.58%
# → word correction rate is 79.76%

But I have this following error :

File “C:\Users\user\Anaconda3\lib\site-packages\torch\serialization.py”, line 764, in _legacy_load magic_number = pickle_module.load(f, **pickle_load_args) UnpicklingError: invalid load key, ‘<’.

Can you help me please ?

Thanks, Camille
