Does anyone know why this is happening?

[Loewen-Hob]

I have the same problem. Have you solved it?

[jalsop24]

I think it stems from the default being wrong here - https://github.com/danielgatis/rembg/blob/0dcdb080ae083de57084c38e93fb210534c5c693/rembg/sessions/sam.py#L153

This is also relevant to #577

This is a character escaping issue. If you are running this from the cmd prompt, it should look like this:

rembg i -m sam -x "{ \"sam_prompt\": [{\"type\": \"point\", \"data\": [724, 740], \"label\": 1}] }" .\1305696_1704870215425_1705054411.png xxx.png

If you're running from PowerShell 5.1, it should look like this:

rembg i -m sam -x '{ \"sam_prompt\": [{\"type\": \"point\", \"data\": [724, 740], \"label\": 1}] }' .\1305696_1704870215425_1705054411.png xxx.png

If you're running from PowerShell 7.4, it should look like this:

rembg i -m sam -x '{ "sam_prompt": [{"type": "point", "data": [724, 740], "label": 1}] }' .\1305696_1704870215425_1705054411.png xxx.png

I got the same error on the HTTP server.

How to solve this when using it interactively on the HTTP server?

The error reporting location should be located in Link Text It means there is a problem with the json format input of your prompt.

Hello, Try with sam_prompt outside of the session argument. For me it works with the following code :

session_rmbg = new_session(model_name="sam") input ect... output = remove(input, session=session_rmbg, sam_prompt=[{"type": 'point', "data": [1600, 2400], "label": 1}])
