I’ve tried to duplicate your notebook, as shown in last night second-half.
It works fine when I use “regular” model names in Cell #3 as
arch=resnet50 (or resnet101), though with lower accuracy (0.89 vs 0.92)
But if I enter
arch=resnext101_64, when I run the first
learn = ConvLearner.pretrained(arch, data, precompute=True), it generates an error as:
Preformatted text`FileNotFoundError: [Errno 2] No such file or directory: ‘/media/eric/SSD500/fastai-master2/courses/dl1/fastai/weights/resnext_101_64x4d.pth’
I did a
git pull a few minutes ago, no fix.
