Some errors when running this demo

[leonwanghui]

Hi Dr.Xiao, recently I'm trying to deploy the mindspore-jina-example demo on my Linux server, but it seems that some errors just occurred unexpectedly.

Firstly it seems that the Jina hello-world couldn't launch successfully on the Linux server with some errors of no browser support. So I'm wondering if the demo can only be installed on Linux with GUI support.

Then when I tried to install the demo with the instruction, some errors occurred when I run jina hello-world --uses-index helloworld.flow.index.yml --uses-query helloworld.flow.query.yml command:

ERROR:tornado.general:Uncaught exception in ZMQStream callback

Could u offer some suggestions to resolve the errors? Thanks!

This looks like a version mismatch problem. The in-docker Jina version & out-docker (aka host machine) Jina version are inconsistent. Try the following steps:

1. pip install -U jina[hub]
2. Rebuild the mindspore-lenet image

If no browser then you can't see the result, but HTML is generated anyway, you can copy-paste the HTML to local and check that.

maybe let me freeze the version

@hanxiao Sure, plz let me know if it's done, thx!

Also there is a tiny error in both helloworld.flow.index.yml and helloworld.flow.query.yml file that the docker image version should be updated to 0.0.2.

@hanxiao Hi, it seems that the demo just work fine on the Linux server. I uninstalled all packages and re-install them through the instruction, the teminal shows that the static hello-world.html page has been generated, and I can open the static website after copying them to my laptop.
