Glaring, impactful bug #51

Closed albertwujj closed 5 years ago

albertwujj commented 5 years ago

Using the following script on Ubuntu 18.04 breaks:

import minerl
data = minerl.data.make('MineRLNavigateExtremeDense-v0')
pov_shape = (64,64,3)

for obs, rew, done, act in data.seq_iter(num_epochs=1, max_sequence_len=32):
    for x in obs['pov']:
        if x.shape != pov_shape:
            print(f'mineRL bug, pov shape: {x.shape}')

May you please respond? The observation shape for 'pov' should clearly be (64, 64, 3), but if you run the above you'll see (at least on my computer), that it is sometimes (64 times 3, 64 times 4, 3).

@brandonhoughton Can you please address this. Even if you make a hotpatch for the data sequence iterator to ensure the correct data is drawn; we need to fix this.

@albertwujj Oni t!
