No module named 'point_sam'

[ChengZY]

Traceback (most recent call last): File "/data1/zhongyao/dl/Point-SAM/demo/app.py", line 5, in from point_sam import build_point_sam ModuleNotFoundError: No module named 'point_sam'

I tried pip install git+https://github.com/zyc00/Point-SAM.git and python setup.py install

... Installed /home/zhongyao/anaconda3/envs/psv2/lib/python3.9/site-packages/point_sam-1.0-py3.9.egg Processing dependencies for point-sam==1.0 Finished processing dependencies for point-sam==1.0

The package should be installed and I can see it in site-packages folder, /home/zhongyao/anaconda3/envs/psv2/lib/python3.9/site-packages/point_sam-1.0-py3.9.egg

but it can not import module ModuleNotFoundError: No module named 'point_sam'
