Running the custom kernel example - error when starting kernel from JupyterLab

[rathboma]

When going through the custom kernel example everything starts correctly in k8s, but when starting the kernel from the notebook it produced a 500 HTTP error:

Seems like the error is some version incompatibility with enterprise gateway. Here are the logs from the gateway:

Error: TypeError: __init__() got an unexpected keyword argument 'kernel_id'

This seems related to this issue: jupyter-server/enterprise_gateway#1024

Seems like it's using jupyter-client 7.1.0, which might be the problem? I'll try to confirm

[gaocegege]

Can you please show the image tag of the gateway and kernel?

[ycsong1212]

Hello, could I know whether you solve this problem? I meet the same issue, I check the version of jupyter_client is 7.1.0. Could changing the version of jupyter_client work? I try to deploy with enterprise-gateway alone instead of elastic-jupyter-operator, that works. I'll appreciate it if you could help.

[ycsong1212]

Can you please show the image tag of the gateway and kernel?

Hello, Mr. Gao. I meet the same question. I try the demo as quick-start but it doesn't work. The tags of my gateway and kernel are both 2.6.0. I want to know whether some version conflict exists. I have tried deploying only with enterprise-gateway and it works. I am interested in what kind of differences between your images and theirs. I am sorry I cannot access your image information and I do not obtain the answer in your code. I'll appreciate it if you could help.

[gaocegege]

OK I will verify it today.

@ycsong1212 Did you follow the guide here? https://github.com/skai-x/elastic-jupyter-operator/tree/master/docs#remote-kernels

@ycsong1212 Did you follow the guide here? https://github.com/skai-x/elastic-jupyter-operator/tree/master/docs#remote-kernels

Remote kernel or Remote kernels with custom configuration

I think I do. First I apply crds by prepare.yaml and then make deploy. I tried elastic-with-custom-kernels demo. I apply four crds under examples/elastic-with-custom-kernels directory. Then I port-forward my notebook pod. When I launch kernel, kernel error occurs. Such error is reported in gateway container.

[DianaDai]

I have same error， how can i fix it?

I did not reproduce it before. I will take a look ASAP but not sure if I can reproduce this time.

It looks like a version problem related to enterprise gateway.

This seems related to this issue: jupyter-server/enterprise_gateway#1024

Seems like it's using jupyter-client 7.1.0, which might be the problem? I'll try to confirm

I encountered the same issue, have you resolved it?
