@wendaizhou Thanks for the fix. There's some additional problems in the build test:

=========================== short test summary info ============================

To run the test locally, you may set up the test files:

mkdir mmhuman3d_download
cd mmhuman3d_download
wget -O mmhuman3d.7z -q https://openmmlab-share.oss-cn-hangzhou.aliyuncs.com/mmhuman3d/mmhuman3d.7z
7za x mmhuman3d.7z
ls -l
cd ..
cp -r mmhuman3d_download/mmhuman3d/* ./
rm -rf mmhuman3d_download

and then run pytest:

pytest tests/test_models/test_body_models/test_star.py

Hi, thanks for the guidance. The bug mentioned in build test has been fixed, but I'm not sure if codecov in failing checks needs to be handled.
