All patches being ignored

[mhchu]

In both the CLI and the GUI version, all the URLs I have tried so far result in all patches being ignored because length(patch.shape) is 2 instead of 3.

For example (the first tutorial Ode to Joy):

$ flowkey-dl-cli https://.../150/0.png

Did flowkey change their image format resulting in this behavior or is my python setup incorrectly configured?

I checked the link you used, it worked fine on my system. I guess it has to do with the version of imageio but both versions I tried, imageio-2.13.3 as well as imageio-2.19.3 did not replicate the issue. Anyway, I tried to handle the case, assuming that the reader returns a b/w image. Let me know if this resolves the issue. Also, I used the update to publish the package on PyPI, so you can now install directly from there without cloning the github.

Also, please do not publish any links (not even from the free songs), I do not want to give flowkey any reason to shut this down. Can you please censor them in your text?

Thanks! I've update my post to remove links. Maybe this problem is unique to me or it could be my imageio version (I'm on 2.4.1). I'm also running this on Ubuntu installed via Windows Subsystem for Linux so there are a bunch of unusual things in my situation. I'm unable to try additional things to see how to fix this because my subscription to flowkey just expired yesterday. I'll go ahead and close this issue.
