Some installation issues

[luolai123]

I am very interested in your project on encirclement, but I encountered some issues during installation and deployment, mainly due to incompatible installation packages and ffmpeg issues. Can you update the following readme and write some explanations?

Can you provide an example of the error message you are receiving?

Animations are built using the matplotlib.animation library. For starters, ensure you have ffmpeg installed:

sudo apt-get install ffmpeg

... of, if using conda:

conda install -c conda-forge ffmpeg
