cannot import name 'torchvision_ssl_encoder'

See original GitHub issue

Hi I just want to run following example, but I get this error “cannot import name ‘torchvision_ssl_encoder’”

from pl_bolts.utils.self_supervised import torchvision_ssl_encoder

resnet = torchvision_ssl_encoder('resnet18', pretrained=False, return_all_feature_maps=True)
x = torch.rand(3, 3, 32, 32)

feat_maps = resnet(x)

Is something wrong with pytorch-lightning-bolts?

I can confirm this issue on master

seems like we have cyclic import somewhere…

I have bolts version ‘0.3.4’ and I am still getting the error. This is the error trace from a jupyter notebook.
