System Info

Severity

Blocking usage of gradio

[dwipper]

upgraded both Spaces to 4.1.1 . Still the same error message.

[dwipper]

upgraded both Spaces to 4.5.0 . Still the same error message.

@abidlabs @freddyaboulton Hi guys, I upgraded both Spaces to 4.7.1 . Still having this issue. It's a blocker that's preventing us from deploying our app to any users. Can you please take a look? Thanks!

[dwipper]

@abidlabs I upgraded both spaces with: https://gradio-builds.s3.amazonaws.com/c884e5eeb35bdf8b86153ede1e8500ac1bca25f6/gradio-4.7.1-py3-none-any.whl , based on the close out of #6602 (#5927, #6388) . The above spaces are both public, so maybe not the same issue mentioned in those issues?

Still throwing the same error.......

[vitaliy-sharandin]

They haven't released a version with the fix yet, that's why it's not working.
https://www.gradio.app/changelog
Latest release has code from Nov 23, fix was merged Nov 30.

[dwipper]

@vitaliy-sharandin Ah, good to know. This is a total blocker for our deployment. Hopefully it comes out soon!

@abidlabs I upgraded both spaces to: https://gradio-builds.s3.amazonaws.com/40f68f9464d880c07e458c2cb865402828edaab5/gradio-4.9.1-py3-none-any.whl

[abidlabs]

I think I know the issue, will put out a fix for this, thanks @dwipper

[ZuzooVn]

@abidlabs your fix works like a champ for public repo like

io = gr.load("spaces/gradio/test-gr-load")
io.launch()

but for the private repo with hf_token, I still receive this error:

ValueError: Could not load https://xxxxxxhf.space/. Please login.

Do you have any recommendations? Thanks
