404 error while running as server

[wmmxk]

The error I run yesterday might be similar to yours. I created a python environment from scratch and it worked. BTW, did you run yarn && yarn build successfully?

[iftenney]

@kumarvrsec did the above (building the client) resolve this?
Yarn needs to run to compile the typescript and produce the main.js file; we've set it to also copy the other static assets into the build directory.

[dsvrsec]

yeah ,I am able to resolve that issue,but I am facing another issue frequently.

[iftenney]

That's odd - possible that you're running from an environment that can't access the hosted files for HuggingFace Transformers?

If so, you can manually download from https://huggingface.co/bert-base-uncased#list-files and pass a pass to that directory instead of the model name.

@iftenney i have met the same problem as this issue, and the teriminal shows :

but the file"index.html" has already been in the path, also i can not open this file with google chrome.
So, please help me to solve the problem, thanks!
i have checked my environment with the yml file and create a python conda envo, but it still can not work.
my systemt is windows11, pycharm, google chrome.

Did you run yarn && yarn build?

[SubtleTom]

Did you run yarn && yarn build?

yes, i have used yarn(on window system) to test my version. and it still can not work.

Hard to tell without seeing what's in the path, you mentioned pycharm - I'm not sure if that might interact with the paths?
This is the code that fetches the static files - you could try debugging from here: https://github.com/PAIR-code/lit/blob/main/lit_nlp/lib/wsgi_app.py#L37

(Unfortunately, we don't have official Windows support for this project, if you're not able to resolve with your regular Windows enviroment you might try running under WSL?)

ok，i will try to test my path, or i may need to use WSL. thanks!
