Thanks for the recommendation! I hadn't looked PyQtGraph before but it looks like a potentially great candidate. If I had known about this earlier (and it's development was far enough...

As of commit 165a5036a3617e2bc45a1a72a8c4ea1f253a25f7 (from branch `python3`), all unit tests pass under python 2.7, 3.3, and 3.4 from the same code base. The only functions remaining to be updated for...

@lewismc Not sure what you confirming - that it does work or doesn't work? I received an email copy of you comment that also include a comment about Travis-CI, which...

Thanks for the error report and additional info. I don't currently have access to a Windows system with python 3.9. Perhaps you could check a few additional things: 1. Did...

I've added python 3.9 to the build matrix for unit testing and it passes (on ubuntu): [https://github.com/spectralpython/spectral/actions/runs/1072623339](https://github.com/spectralpython/spectral/actions/runs/1072623339)

What happens if you set the interpolation to "nearest"? view2 = spy.imshow(classes=gt, title='gt', interpolation='nearest')

The module does not currently have a way to display a color legend. If that is something you need, you could call `spy.get_rgb` instead, which accepts the same parameters, then...

What happens if you try this: ``` import logging logging.getLogger('spectral').setLevel('DEBUG') print(img.shape) mm = img._open_memmap("r") print(mm.shape) ```

Ah, I didn't notice it was python 2.x. And if it was 32-bit python, then `memmap` would not work on an image that large.

Out of curiosity, what does this print for your python version: ``` import sys print(sys.version) print(sys.maxsize) ```
