Hello, I was able to install sagecell according to the *Installation *instructions at https://github.com/sagemath/sagecell with 2 differences: in step 2 I didn't source sage from github, but used a 9.6 version of sage compiled from source, and in step 4 I passed the argument -B to make to force rebuild. The installation has completed successfully.
Afterwards, I tried to launch the sagecell server directly according to the Step 5 of *Configuration *instructions from https://github.com/sagemath/sagecell . (As I work on a private and firewalled server, I didn't set up any ssh account/keys for now and I didn't change anything in config.py, web_server.py or log.py files, but left them as they were originally.) Launching sagecell as in* Step 5 * *$ ../sage/sage-9.6/sage web_server.py -p 8888 &* produced the error posted below. The surprising part is, a colleague of mine was able to follow the *Installation* instructions of sagecell from https://github.com/sagemath/sagecell some time ago and then proceeded directly to Step 5 of *Configuration *as I did (i.e, without setting up ssh or changing anything in config.py or log.py) and he could launch the sagecell server with no errors. Could anyone advise me on where my error could come from and how can try to fix it? Something is wrong with tornado (first warning, current loop missing) and paramiko (last warning)... But I have no idea what the problem could be. Thanks a lot! *ERROR* --------------- varvara@zage:~/sagecell$ /home/varvara/sage/sage-9.6/local/var/lib/sage/venv-python3.10/lib/python3.10/site-packages/tornado/ioloop.py:263: DeprecationWarning: There is no current event loop loop = asyncio.get_event_loop() /home/varvara/sage/sage-9.6/local/var/lib/sage/venv-python3.10/lib/python3.10/site-packages/tornado/platform/asyncio.py:279: DeprecationWarning: There is no current event loop super().initialize(asyncio.get_event_loop(), **kwargs) /home/varvara/sage/sage-9.6/local/var/lib/sage/venv-python3.10/lib/python3.10/site-packages/zmq/eventloop/zmqstream.py:101: DeprecationWarning: zmq.eventloop.ioloop is deprecated in pyzmq 17. pyzmq now works with default tornado and asyncio eventloops. self.io_loop = io_loop or IOLoop.current() Traceback (most recent call last): File "/home/varvara/sagecell/web_server.py", line 147, in <module> app = SageCellServer(args.baseurl, args.dir) File "/home/varvara/sagecell/web_server.py", line 79, in __init__ start_providers(self.kernel_dealer.port, config.get("providers"), dir) File "/home/varvara/sagecell/web_server.py", line 39, in start_providers client.connect(config["host"], username=config["username"]) File "/home/varvara/sage/sage-9.6/local/var/lib/sage/venv-python3.10/lib/python3.10/site-packages/paramiko/client.py", line 435, in connect self._auth( File "/home/varvara/sage/sage-9.6/local/var/lib/sage/venv-python3.10/lib/python3.10/site-packages/paramiko/client.py", line 766, in _auth raise saved_exception File "/home/varvara/sage/sage-9.6/local/var/lib/sage/venv-python3.10/lib/python3.10/site-packages/paramiko/client.py", line 742, in _auth self._transport.auth_publickey(username, key) File "/home/varvara/sage/sage-9.6/local/var/lib/sage/venv-python3.10/lib/python3.10/site-packages/paramiko/transport.py", line 1635, in auth_publickey return self.auth_handler.wait_for_response(my_event) File "/home/varvara/sage/sage-9.6/local/var/lib/sage/venv-python3.10/lib/python3.10/site-packages/paramiko/auth_handler.py", line 259, in wait_for_response raise e paramiko.ssh_exception.AuthenticationException: Authentication failed. ---------------------------------- -- You received this message because you are subscribed to the Google Groups "sage-cell" group.
