Quick fix for KeyError: 'dataset'

[jtydhr88]

Hi there,
If you are facing KeyError: 'dataset' issue, you can fix by:

1. go to your webui_folder\venv\Lib\site-packages\gradio_client and edit serializing.py file
2. go to the end of the serializing.py, and add one line inside COMPONENT_MAPPING:
   "dataset": StringSerializable,
   it should look like after modifing:
   
3. Save
4. Restart your webui.

it should work well now, I tested 900 hands on webui latest version 1.5.1 + gradio 3.32.0 + gradio_client 0.3.0

it should fix the issues:

1. can't start extansion after install #32
2. Error occured when 900 hands installed #35
3. [Bug]: Exception in ASGI application AUTOMATIC1111/stable-diffusion-webui#11855

I know webui plans to update gradio to latest(3.39) in later release v1.6.0 (see richrobber2/canvas-zoom#88), but likely it still lost dataset map in https://github.com/gradio-app/gradio/blob/v3.39.0/client/python/gradio_client/serializing.py

there are several ways to fix the issue permanently:

1. I am not sure the reason why gradio miss this code, it may have some reasons, but it could be gradio client bug, should be fixed in gradio side.
2. replace the code

   sd-webui-depth-lib/scripts/main.py

   Line 47 in efa9f61

   dataset = gr.Examples(examples=os.path.join(maps_path, t), inputs=[png_input_area],examples_per_page=24,label="Depth Maps", elem_id="examples")

   using gr.Examples by another way to show the image lib, may could be gallery component https://www.gradio.app/docs/gallery I guess.
3. totally give up gradio component and use other tech, like pure javascript instead to display the image lib (as a webui extension developer, I prefer to rebuild my page by HTML/CSS/JS rather than using gradio honstlly)

Hello. Thank you, helped with the replacement serializing.py

Do you know why don't show pictures? There are no errors in the console. I think it's because of the symbolic link to the extension #29

@alexbofa i don’t see the issue that images not show up on my side, I tested the default images from this extension and 900 hands, and they work well. If you could provide more information I may help.

works for me also

gr.gallery solution looks okay and possible

I didn't have time to fix the message, because I found a problem in the issue. It's possible, as I wrote in the updated post, that the problem is that I'm using a symbolic link for "Extensions" #29

2. by another way to show the image lib, may could b

dataset = gr.Examples(examples=os.path.join(maps_path, t), inputs=[png_input_area],examples_per_page=24,label="Depth Maps", elem_id="examples")

Should be replaced by what?
