trackformer: Not able to install MultiscaleDeformableAttention

Hi,

I am trying to run a test for training trackformer. I am looking at INSTALL.md to build the environment. When I try python src/trackformer/models/ops/setup.py build --build-base=src/trackformer/models/ops/ install I get an error saying:

Traceback (most recent call last):

How can I get this package installed?

Thanks,
