jina: Flow/Deployment would raise timeout warning even if containerized executor is running

Describe your problem

---

I follow the tutorial here and create my own docker image called “my_exec” for an executor. It works perfectly when I use jina executor --uses docker://my_exec to serve the executor and use a Client object to use it. However, serving by using a Flow or a Deployment object would always raise a timeout warning and hang indefinitely as shown in the following screenshots.

My executor needs to load a large neural net to initialize, which takes about 1 minute. I thought this loading time could be the cause of the problem and tried setting timeout-ready to -1, but I still cannot get rid of this warning.

Another possible cause maybe that the entrypoint of my docker image is ENTRYPOINT ["conda", "run", "-n", "legacy_subtitle_punc", "jina", "executor", "--uses", "config.yml"] where I activate a conda environment before calling jina instead of calling jina directly. Does this have something to do with the problem? If it is the cause, are there any workarounds that still allow me to use conda?
