Cannot import name 'tensormask' from 'detectron2.projects'

I followed the setup of https://github.com/facebookresearch/detectron2/tree/main/projects/TensorMask. But still I can not import it. As I can with from detectron2.projects import point_rend.

I run the below line.
pip install -e /path/to/detectron2/projects/TensorMask

Still no luck

ImportError                               Traceback (most recent call last)
Cell In[62], line 1
----> 1 from detectron2.projects import tensormask

ImportError: cannot import name 'tensormask' from 'detectron2.projects' (/kaggle/working/detectron2/detectron2/projects/__init__.py)

I read some of the solutions, but they are vague. Some suggested that to change the name of detectron2 directory will solve it. But for me it is not.
