@jeremy When I started running the notebooks, I came crossed “cannot find module bcolz”. So, I installed bcolz individually. However, I got an error message saying bcolz was installed. I removed everything and reinstalled the whole repo by using download zip file from GitHub instead of git clone. However, no improvement. I found others discussing similar problem in Paperspace few days ago. But, no solution in the forums. Any idea? In the meantime, I will use AWS.
