python - Cannot load pickled object -
the problem having when try load pickled object. have tried using both pickle.loads , pickle.load here results:
pickle.loads - typeerror: 'str' not support buffer interface
pickle.load - typeerror: file must have 'read' , 'readline' attributes
can please tell me doing wrong in process? thanks, , here code:
elif str(parser) == 'swisswithdrawn_parser': # swissprot name changes print('gathering swissprot update info...') cache_hits = 0 cache_misses = 0 files = set() f in os.listdir('out/cache/'): if os.path.isfile('out/cache/'+f): files.add(f) name in sp_lost_names: cached = false url = 'http://www.uniprot.org/uniprot/?query=mnemonic%3a'+name+ \ '+active%3ayes&format=tab&columns=entry%20name' hashed_url = str(hash(url)) ################### testing - use cache ################## if hashed_url in files: cached = true cache_hits += 1 content = pickle.loads('out/cache/' +hashed_url) # <-- problematic line else: cache_misses += 1 content = urllib.request.urlopen(url) # contents returned httpresponse object content_list = [x.decode().strip() x in content.readlines()] if not cached: open('out/cache/'+hashed_url, 'wb') fp: pickle.dump(content_list, fp) #################################################################### # no replacement if len(content_list) 0: change_log['swiss-names'] = { name : 'withdrawn' } # new name else: new_name = content_list[1] change_log['swiss-names'] = { name : new_name }
you need either read file first (as binary bytes) , use pickle.loads(), or pass open file object pickle.load() command. latter preferable:
with open('out/cache/' +hashed_url, 'rb') pickle_file: content = pickle.load(pickle_file) neither method supports loading pickle filename.
