i typed an email and it went away the last model from last email was corrupt, download is broken. here are checksums for a large model and smaller swin models: c7a3cc5bdd743507e44b4254b81621bf6ac0253d52506a7569d24bef03ad0528 ircsn_ig65m-pretrained-r152_8xb12-32x2x1-58e_kinetics400-rgb_20220811-c7a3cc5b.pth 7cb0556d8147be647601e6fa3ac7175f0d59e50bb6be66fd61e9ad964b767cc4 ircsn_ig65m-pretrained-r152_8xb12-32x2x1-58e_kinetics400-rgb.py e91ab986e24280425f1b5ea0851e4a9c194b6409bf12772d47761542d1bb53a3 swin-small-p244-w877_in1k-pre_8xb8-amp-32x2x1-30e_kinetics400-rgb_20220930-e91ab986.pth 0c03449f4e7476f4c0b3307e0eb440e4c3eb1dec5efdeeee93d5d97955434840 swin-small-p244-w877_in1k-pre_8xb8-amp-32x2x1-30e_kinetics400-rgb.py 241016b2a95f8cf039fea2948be1fe5889b0ed319cda7f4e5b7dbd5ac2b89851 swin-tiny-p244-w877_in1k-pre_8xb8-amp-32x2x1-30e_kinetics400-rgb_20220930-241016b2.pth a6ba5eaf50f46808451c6c63eb3c6aff3b1aa280684249e7c45fa53115526350 swin-tiny-p244-w877_in1k-pre_8xb8-amp-32x2x1-30e_kinetics400-rgb.py i did not try swin-small. both swin-tiny and ircsn gave 99% accuracy for the arm wrestling example, much better than the 2018 model. ircsn was very very slow. swin-tiny is still likely not quite fast enough to perform live analysis on my system without something added, like a framerate drop.
