Local Enterprise Gateway fails to start kernel with "Fatal Python error: failed to get random numbers to initialize Python"

[averageflamethrowerguy]

I hate to spam you, Kevin.

I'm doing a local basic Enterprise Gateway local install (hopefully for more websocket testing in the future!)

Here's my setup (following the general guide). I did the clean install to make sure the error wasn't specific to my original environment.

conda create --name gateway python=3.6
conda activate gateway
conda install -c conda-forge jupyter_enterprise_gateway

I then start Enterprise Gateway with

jupyter enterprisegateway --ip=0.0.0.0 --port_retries=0 --log-level=DEBUG

which launches the Gateway on port 8888.

and my notebook with

jupyter notebook --gateway-url=http://localhost:8888 --port=7000 --GatewayClient.http_user=guest --GatewayClient.http_pwd=guest-password

in a different terminal.

Both processes initially function fine. /api/kernelspecs returns correctly, the kernel starts, then refreshes. The "Fatal Python error: failed to get random numbers to initialize Python" fails then.

Here's the detailed logs:

Fatal Python error: failed to get random numbers to initialize Python

AsyncIOLoopKernelRestarter then takes over and repeats the start-stop-refresh-fail sequence five times.

A quick Google suggests this may have something to do with environment variables, if it's at all helpful.

[kevin-bates]

Hi Elliot, we have never officially qualified EG on Windows and I'm wondering if this is something related to that. I have personally never seen "Fatal Python error: failed to get random numbers to initialize Python" before. But let's keep plugging away here.

If the auto-restarts are happening, then that means the popen call is completing (to launch the kernel process), but the process itself is not getting off the ground. There should be a series of auto-restarts as you imply. Could you please provide at least one complete sequence of log messages for that?

We do pass env variables to the subprocess - which is evident in the last debug entry above. However, I believe this is not the case with the standard notebook server, in which case the env passed to the subprocess will be a copy of the notebook server's env. As a result, envs like SYSTEMROOT won't necessarily be present.

Could you please try the following? Start your EG server with this option:

--EnterpriseGatewayApp.env_process_whitelist="['SYSTEMROOT']"

This will transfer the value of the SYSTEMROOT env from the process to the kernel subprocess. It's a list-valued property, so there might be others, but I would recommend just adding one at a time. If you run into issues setting this on the command line, the following env could be set instead, which simply takes a comma-separated list of strings...

EG_ENV_PROCESS_WHITELIST=SYSTEMROOT

[averageflamethrowerguy]

You're right. This is almost certainly a Windows-specific error.
I did a simple deployment with the method in the docs on an EC2 instance and it worked beautifully.

The SYSTEMROOT variable was also a good call -- the original error is resolved.
The newer error is

Bad file descriptor (D:\bld\zeromq_1605919615529\work\src\epoll.cpp:100)

and may have something to do with file cleanup by Python.
I have no idea why Python would be trying to create and clean up files in my data drive, though.

Now that I've got a EC2 deployment running for cross-testing, I'll probably go and chew on the Kubernetes problem for a while. I'm happy to work with you more on getting EG operational on Windows, too, depending on whether you want to support Windows in the future.

Here are the (new) full logs, if you're interested.

Bad file descriptor (D:\bld\zeromq_1605919615529\work\src\epoll.cpp:100)

and may have something to do with file cleanup by Python.
I have no idea why Python would be trying to create and clean up files in my data drive, though.

Theses are zmq sockets getting cleaned up (per the linked issue) where their closing is likely the responsibility of code in the jupyter_client package. The file referenced int he Bad file descriptor message is the source code that is encounter the bad file descriptor (associated with a socket).

What's strange is that you're running a LocalProcessProxy as evidenced by this log entry:

[D 2020-12-02 14:31:36.629 EnterpriseGatewayApp] Instantiating kernel 'Python 3' with process proxy: enterprise_gateway.services.processproxies.processproxy.LocalProcessProxy

and the LocalProcessProxy is really nothing more than a pass-thru to the regular code in jupyter_client. I'd be curious if you see similar behaviors running the same notebook w/o using the --gateway-url option when starting the notebook server. (Just be sure the notebook server is invoked in the same environment in which you're currently attempting to run EG.)

I'm happy to work with you more on getting EG operational on Windows, too, depending on whether you want to support Windows in the future.

Since I believe you might be the first to go down the Windows road, it might be worthwhile attempting to understand what are actual issues vs. what might be environmental/configuration-related. But that's completely up to you since I don't really have a system to try things out on (although I can probably get one provisioned from my employer for a time being).

Given your primary target is Kubernetes and since EG needs to run in a pod, it's probably not really worth your time going down this road (although I think we should probably perform the test of running a straight notebook server in the EG env).

Thanks.

[averageflamethrowerguy]

Yes, the standard notebook runs fine in this environment

(gateway) C:\Users\Operator>jupyter notebook --port=7000

and the port doesn't matter.

I probably will poke at this issue a bit more from time to time. I agree with you that getting a better sense of what the issues with Windows are and where they arise may be valuable, and EG seems like a useful enough project that I'm happy to help!

[kevin-bates]

Hi @averageflamethrowerguy - although I'm afraid to ask (:smile:) have you made any progress on this for Windows?

[averageflamethrowerguy]

The fear is justified. No progress. I'm also no longer at the company where I was using EG stuff, so I doubt I'll touch this again. Sorry!

[kevin-bates]

No worries Elliot. That Help Wanted label should do the trick! Good luck at your new gig.
