03_logreg.py- My Jupyter notebook couldn't download the MNIST file.

[frankburg]

I ran the 03_logreg.py file but it couldn't download the MNIST file.
Look at the error it throws below, what could be the cause.

1. do directory data/mnist/ exist ??
2. do file train-images-idx3-ubyte.gz is there ???
3. in case not maybe try to place it there manually and repeat to check if there problem with download or problem with path to file after download.

I met the same error, and I resolved it. You have to creat the directory data/mnist/ manully on your disk.

The reason why you meet this issue is you are using Windows OS.
Just find out where we defined the file path, and modify the “train-images-idx3-ubyte” to “train-images.idx3-ubyte”
