decord​

error: Distribution `decord==0.6.0 @ registry+https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple` can't be installed because it doesn't have a source distribution or wheel for the current platform
hint: You're on Linux (`linux_x86_64`), but `decord` (v0.6.0) only has wheels for the following platforms: `manylinux2010_x86_64`, `win_amd64`; consider adding your platform to `tool.uv.required-environments` to ensure uv resolves to a version with compatible wheels
