ImportError: cannot import name 'imresize'

[maivincent]

When running in gym-duckietown conda environment

python -m reinforcement.pytorch.train_reinforcement

I get this error:

 File "/home/vincent/gym-duckietown/learning/utils/wrappers.py", line 18, in observation
    from scipy.misc import imresize
ImportError: cannot import name 'imresize'

I looked a bit and it seems that imresize is deprecated in scipy as written here in Backwards incompatible changes: https://github.com/scipy/scipy/releases/tag/v1.3.0rc1

Could this be the source of the problem?

Yeah likely; let me see if there's a fix for this in the new ones.

[bhairavmehta95]

Good catch.

[maivincent]

Fix did induce a new bug:

    return np.array(Image.fromarray(observation).resize(shape))
NameError: name 'shape' is not defined

[maivincent]

@bhairavmehta95 : return np.array(Image.fromarray(observation).resize([self.shape[0:1]])) should be the fix.

[bhairavmehta95]

Wouldn't it be self.shape? The splice (means: from index 0 to 1 exclusive, so just 0) above would resize to a single dimension = square of shape[0] x shape[0]

[maivincent]

Woops, then it should be self.shape[0:2] sorry. It does not accept the 3 args of self.shape, as resize takes in only 2. I figured that shape being defined as shape=(120, 160, 3)), only 120 and 160 are needed.
