In the previous GitHub workflow, installation of Pillow==6.2.2 is useless because it will be overwritten afterward in
pip install -r requirements.txt
. The actual version installed finally is 8.4.0. This version is compatible with old torchvision becausePILLOW_VERSION
is re-imported (which is removed in version 7), so previous CI works until 2022-Jan-02 when Pillow 9 was released. So I tried to use Pillow<9 to keep this compatibility with old-versioned torchvision as well as other dependencies.
