What do you need to change/add¶
if you installed ffmpeg-python
in your conda env:
conda install -c conda-forge ffmpeg
you only need to modify the kernel.json
to add the PATH
of the
ffmpeg
like this:
{
"argv": [
"/path/to/your/conda/env/bin/python",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"display_name": "my kernel",
"language": "python",
"env": {
"PATH":
"/sw/rhel6-x64/graphics/ffmpeg-3.4.1-gcc64/bin:/path/to/your/conda_env/bin:$PATH"
}
}
