Imagemagick and Streamlit

[RafaSarg]

Basically I’m using moviepy which has some components that depends on imagemagick and although I am putting imagemagick in my packages.txt file, it is still bringing up this error:

File "/home/appuser/venv/lib/python3.10/site-packages/streamlit/runtime/scriptrunner/script_runner.py", line 552, in _run_script
    exec(code, module.dict)
File "/app/reddittotiktok/TikTok-Voice-TTS-main/frontend.py", line 28, in <module>
    make_video(subreddit, listing, limit, timeframe)
File "/app/reddittotiktok/TikTok-Voice-TTS-main/utils.py", line 256, in make_video
    word_subtitle_clips = generate_subtitle_clips(word_subtitles)
File "/app/reddittotiktok/TikTok-Voice-TTS-main/utils.py", line 244, in generate_subtitle_clips
    word_clip = TextClip(line, fontsize=24, color='white').set_duration(duration).set_position(('center', 'center'))
File "/home/appuser/venv/lib/python3.10/site-packages/moviepy/video/VideoClip.py", line 1146, in init
    raise IOError(error). 

I’m not quite sure what it means, but I think moviepy isn’t detecting imagemagick in streamlit. Also yes this does work on my local computer, I’m trying to put this on Streamlit cloud though. Also getting this in the terminal:

convert-im6.q16: attempt to perform an operation not allowed by the security policy @/tmp/tmpoyfdc8ce.txt' @ error/property.c/InterpretImageProperties/3708.

convert-im6.q16: no images defined PNG32:/tmp/tmpsok8w3pu.png' @ error/convert.c/ConvertImageCommand/3229.

This error can be due to the fact that ImageMagick is not installed on your computer, or (for Windows users) that you didn't specify the path to the ImageMagick binary in file conf.py, or that the path you specified is incorrect

Hi @RafaSarg, and welcome to our community!

From your error log, it seems you’re having an issue with ImageMagick’s policies on Streamlit Cloud. Here’s the specific error:

convert-im6.q16: attempt to perform an operation not allowed by the security policy '@/tmp/tmpoyfdc8ce.txt' @ error/property.c/InterpretImageProperties/3708.

Have you checked Chanin’s suggestion here to fix this issue?

How to access the terminal for an app deployed on Streamlit?

Hi @Bart_Eshwar I don’t think it is possible to get terminal root access with a deployed app on Community Cloud. However, you might want to fork a copy of the package (if available on GitHub) then edit the file. Afterwards you can install the custom package via requirements.txt by following instructions from the Knowledge base article Hope this helps! Best regards, Chanin

Best,
Charly

Hey @RafaSarg ,

Yeah, Streamlit does have security policies that prevent this.

I think your best approach now would be to have your Imagemagick image processing code up on a VM, another server or simply, your own api.

I think you could whip up a fast api or flask endpoint to handle this logic and use streamlit to make requests to this api.

This should help avoid you running into Streamlit’s client side security issues.

Let me know if this works!
