lesson2-sgd notebook gets an error for the following cell:
plt.scatter(x[:,0],y)
plt.scatter(x[:,0],x@a);
The last line of the long traceback says:
RuntimeError: Can't call numpy() on Variable that requires grad. Use var.detach().numpy() instead.
I am using the Paperspace + Fast.AI 1.0 (V3) container and followed the setup instructions and the instructions for returning to work.
