I’m going over the dogs/cats linear model in lesson 2, and I’m seeing this error when using
Exception RuntimeError: RuntimeError('fatal error during Blosc decompression: -1',) in 'bcolz.carray_ext.chunk._getitem' ignored
It only happens when I’ve saved and then loaded the training features using bcolz (not the validation features - I’ve checked). It happens no matter how many epochs. The exception repeats 55 times (which is a strange number - batch size is 64, training sample is 200, validation sample is 40). I’ve tried restarting the kernel - no change.
At the end of the day it’s not that big a deal - there’s no error if I skip using bcolz (and just hold everything in memory). But I’m not doing anything weird - it’s a p2 instance with the standard AMI you gave us for this class.
Here’s what it looks like:
