Yangsuit-Can't 'Load modules' Error 500

saumya003 — Thu, 26 Jan 2023 11:42:03 GMT

I have installed YangSuit (using pip) from github - https://github.com/CiscoDevNet/yangsuite

But, I can't 'Load modules' Error 500 (Input/Output error). Also, I am getting only one option in protocols i.e. NETCONF.

What am i doing wrong? Any help please regarding these 2 problems ?

See the following big here and workaround https://github.com/CiscoDevNet/yangsuite/issues/30 - you might not be seeing RESTCONF, check if this is enabled on your device(s)

Hope this helps.

You need to install the restconf plugin, pip install yangsuite-restconf.

Share the log from the 500 error, what plugin are you using, what workflow is causing the error? Please make sure to use latest versions too!

Hi @senzhiwang73998 can you please which version of Windows are using? Your error states "Windows NT 10" but I'm guessing that just means Windows 10.

Hi @senzhiwang73998,

I just did a fresh install of YANG Suite on my Mac OS Ventura 13.2.1 from Docker following these instructions and this video

Modules added to repo and copied to set without issue

Don't use the IOS XE sandboxes on DevNet to pull the modules because they are not fully online right now 3/30/23.

Hi @senzhiwang73998,

I added the IOS-XE-ethernet module but can't explore it. Here is the reason:

I tried to load the other schema you showed, the IOS XE wireless, but I don't have that module available for the IOS XE I have access to so I can't try it but I can explore other modules.

Hi @senzhiwang73998 ,

Hmmm. You said you installed with Docker. Have you tried to install with Pip instead?
