Image is not supported as a dependency

See original GitHub issue

Version: 0.22.0+f9b30a

I ran this command:

dvc run -d 2018-12-12-13:32:56.png -o derp 'echo derp > derp'

Where the dependency is:

2018-12-12-13:32:56.png: PNG image data, 1228 x 494, 8-bit/color RGBA, non-interlaced

And I got this:

Error: Failed to run command: Dependency '2018-12-12-13:32:56.png' is not supported

Is this intended? Why we aren’t supporting images as dependencies?

look like it’s a URL parser issue - ‘2018-12-12-13’ is considered as a schema (http, https, etc)

Turns out it was actually an issue on our side. Our regex for the local dependency was not smart enough. I will send a patch for this soon.

The --no-exec is a good example of that. But we also need to know which remote type to use for specific dependency/output(mind that this issue also affects outputs) beforehand. We should simply not use regex for local ones at all, and instead, use it as a default type if it doesn’t have some other supported schema.
