I don’t think mnist.pkl.
tgz
exists. Can you try to explicitly specify the .gz
extension instead? Try replacing your second cell with:
path = datasets.download_data(MNIST_URL, ext='.gz'); path
Just to add a bit more explanation:
When running download_data(MNIST_URL')
without specifying the extension (ext='.gz'
), it will default to .tgz
.
In your case it tries to download http://deeplearning.net/data/mnist/mnist.pkl.tgz instead of http://deeplearning.net/data/mnist/mnist.pkl.gz.
If you try to open the first link, it will show a 404 - not found page. What happened is that the library downloaded this html page, which is not a gzipped file, hence the error.
