Any lead on this issue?

Start at tools/demo.py line 14 and follow the import chain through yolox/data/datasets/coco.py to pycocotools.coco and pycocotools._mask. Inspect the NumPy and pycocotools versions in the reported Anaconda environment, then verify that running tools/demo.py completes the import without the binary incompatibility error.
