Hi,

I created a virtual environment as your suggestion. But I got the following error:

Extracting ./data/MNIST\train-images-idx3-ubyte.gz

    return self.train_dataset[start:end], self.train_label[start:end]

Do you know the reason? Thank you very much for your great help.

I found out the reason. There was a little bug. The code in line 20 of Clients.py "self.train_labellabel = self.label" should be "self.train_label = self.label"
