Everything is up to date now :
tensorboard       2.0.0
tensorboardX      1.5
torch             1.3.0
torchtext         0.3.1
torchvision       0.4.1
yet I’m still facing the same problem.
(I’ve also restarted the computer.)
Could it be possible that I have 2 versions of PyTorch on my computer : 1 installed via Pip and 1 via conda ?
