Akousamultiprocessing.AuthenticationErrorAuthentication failed when connecting to a multiprocessing server.
The authentication key used to connect to a multiprocessing Manager or Listener does not match. Both ends of the connection must use the same authkey for the HMAC-based authentication.
Ensure both processes use the same authkey. Set it explicitly: manager = Manager(); manager.start(authkey=b'secret'). For Listener/Client, pass matching authkey parameters. Check that the key is bytes, not str.
SyntaxErrorPython encountered invalid syntax that cannot be parsed.
LookupErrorBase class for errors raised when a key or index is not found (KeyError, IndexError).
ValueErrorA function received an argument of the right type but an inappropriate value.
struct.errorAn error occurred while packing or unpacking binary data with the struct module.
re.errorThe regular expression pattern contains invalid syntax.
FloatingPointErrorA floating point operation failed. Rarely seen unless fpectl is enabled.
