In case this helps someone else:
in the Deep BatchNorm section of the lesson7-cifar10 notebook:
There’s an extra open-parenthesis in the following line:
File "<ipython-input-52-cee3f60287b2>", line 1 learn = ConvLearner.from_model_data((ConvBnNet2([10, 20, 40, 80, 160], 10), data) ^ SyntaxError: unexpected EOF while parsing
You can find it by comparing carefully to the BatchNorm section above.
