In file acrcloud_sdk_python/raspberrypi/python2.7/acrcloud/recognizer.py the function recognize_by_file has 5 parametes with the last one being filter_e . This parameter is used during function call acrcloud_extr_tool.create_fingerprint_by_file(file_path, start_seconds, rec_length, False, filter_e) but this function accepts only 4 parameters whereas 5 are being passed. The filter_e parameter has to be removed and it solves the problem. The changed code that I am able to run successfully is acrcloud_extr_tool.create_fingerprint_by_file(file_path, start_seconds, rec_length, False)
