trimesh was imported after #771 and was added into optional.txt. However, it dit not using try to avoid rasing error when not installing this package. This led to the failure of CI for downstream projects.

Modification

Add trimesh and poseval to requirements/runtime.txt

BC-breaking (Optional)

None.

Will other dependencies in optional.txt lead to the same problem in downstream projects, e.g. pyrender?

mmpose/mmpose/core/visualization/image.py

Lines 14 to 19 in 31c1e10

	try:
	os.environ['PYOPENGL_PLATFORM'] = 'osmesa'
	import pyrender
	has_pyrender = True
	except (ImportError, ModuleNotFoundError):
	has_pyrender = False

These lines avoid this problem.

But poseval will cause the same issue. I think the packages which imported without using try&except should move to runtime. But onnx and onnxruntime are only used in tools, no need to move.
