Hi @cbs-rschreijen this issue was reported by some others as well. Have you installed syft from https://github.com/OpenMined/PySyft@dev#egg=syft link? If yes then uninstall and re-install syft. It should work. Here is the PR for the change OpenMined/PySyft#5312.

If you are in OpenMined slack, you can find how others solved it here.

Thank you Zareen, uninstalling and reinstalling PySyft (effectively upgrading version again) fixes the probleem as you mentioned.

Unfortunately the http://yann.lecun.com/exdb/mnist/train-images-idx3-ubyte.gz download is unavailable right now, but this is not fixable, just have to wait until it becomes available again.

How can I join OpenMined Slack? Is it by invitation only?
