Blenderbot 3 Import Error

[shleeku]

Hi I am trying to run Blenderbot 3 on Ubuntu 20.04 tried with RTX 2080Ti and RTX 3080Ti and it worked exactly once (one turn) after which it keeps giving the same error. I'm in Korea so I'm wondering whether it's because you haven't released it internationally yet (but if so why did it work the first time?) and if so if you could let us know when you plan to release it would be greatly appreciated.

Used the following command in terminal (after setting up environment, installing requirements.txt, etc):

parlai interactive --model-file zoo:bb3/bb3_3B/model --init-opt gen/r2c2_bb3

Got the following error:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

I've got similar error:

The code which I was running, is as follows (stripped down a bit):

Code

class ChatServiceRunner:

  def setup_args(self):
      """
      Set up args.
      :return: A parser that takes in command line arguments for chat services (debug, config-path, password), and a port.
      """
      parser = ParlaiParser(False, False)
      parser.add_argument('--datapath', default=self.dataPath)
      parser.add_argument('--download-path', default=self.downloadPath)
      parser.add_argument('--init-opt', default="gen/r2c2_bb3")

      parser_grp = parser.add_argument_group('Websockets')
      parser_grp.add_argument('--port', default=34500, type=int, help='Port to run the browser chat server')
      parser_grp.add_argument('--debug', dest='is_debug', action='store_true', help='print and log all server interactions and messages',)
      parser_grp.add_argument(
          '--password',
          dest='password',
          type=str,
          default=None,
          help='Require a password for entry to the bot',
      )

      return parser.parse_args()

  def __init__(self, _corePath):
      self.corePath = _corePath
      self.appPath = os.path.normpath(os.getcwd() + os.sep + os.pardir + os.sep + os.pardir) #selects parent dir two levels up
      self.dataPath = os.path.join(self.appPath, "ModelData")
      self.downloadPath = os.path.join(self.appPath, "Downloads")
      print(self.dataPath)
      self.opt = self.setup_args()

Any ideas what could be causing this?

I've installed ParlAI via zip download today, then running setup.py.

Perhaps related to #4731 ?

These commands should work if you have installed directly from source.

We have not made a formal pip release yet including BB3, but that is imminent.

Thanks Kurt, will try installing again
