I'm working with google colab & try to build the DCNv2 model to train LORE-TSR on my custom dataset.

when trying to run the:

!bash make.sh

command i always encounter errors regarding building the '_ext' extension

building '_ext' extension ... fatal error: Python.h: No such file or directory compilation terminated. ninja: build stopped: subcommand failed. ... RuntimeError: Error compiling objects for extension

i installed python, pytorch, cuda version as given in the req.txt file, has anyone encountered the same error? Any idea how to solve?
