Exception in comm_msg #23

Closed DarylWM closed 5 years ago

Hello. I tried to run the simple example and got this exception:

[IPKernelApp] ERROR | Exception in comm_msg for 25f18d07590144fbb24eb3ccacda4741 Traceback (most recent call last): File "/home/ubuntu/anaconda3/envs/py36/lib/python3.6/site-packages/ipykernel/comm/manager.py", line 111, in comm_msg comm.handle_msg(msg) File "/home/ubuntu/anaconda3/envs/py36/lib/python3.6/site-packages/ipykernel/comm/comm.py", line 159, in handle_msg self._msg_callback(msg) File "/home/ubuntu/anaconda3/envs/py36/lib/python3.6/site-packages/jupyter_plotly_dash/nbkernel.py", line 26, in callback response, mimetype = app.process_view(stem, args, app_path) File "/home/ubuntu/anaconda3/envs/py36/lib/python3.6/site-packages/jupyter_plotly_dash/dash_wrapper.py", line 120, in process_view return func(args, app_path, view_name_parts) File "/home/ubuntu/anaconda3/envs/py36/lib/python3.6/site-packages/jupyter_plotly_dash/dash_wrapper.py", line 126, in rv_ mFunc = self.as_dash_instance(base_pathname=app_path).locate_endpoint_function() File "/home/ubuntu/anaconda3/envs/py36/lib/python3.6/site-packages/jupyter_plotly_dash/dash_wrapper.py", line 34, in as_dash_instance base_pathname = base_pathname) File "/home/ubuntu/anaconda3/envs/py36/lib/python3.6/site-packages/django_plotly_dash/dash_wrapper.py", line 179, in form_dash_instance rd.callback(**cb)(func) File "/home/ubuntu/anaconda3/envs/py36/lib/python3.6/site-packages/django_plotly_dash/dash_wrapper.py", line 407, in callback [self._fix_callback_item(x) for x in events]) TypeError: callback() takes from 2 to 4 positional arguments but 5 were given

Evaluating !jupyter serverextension list gives:

` config dir: /home/ubuntu/anaconda3/envs/py36/etc/jupyter jupyter_plotly_dash.serverext enabled

That looks like the recent change in Dash itself to no longer use events with callbacks. Updating to the latest version of django-plotly-dash should resolve this - are you in a position to try this?
