This will help reduce some of the noise from tensorflow. Most of the noise comes from Keras and there isn't a great way to limit it without redirecting all stderr from the library.

This PR also allows eyeballer to produce the --help message when no params are provided. This depends on PR #42

I'm still getting pretty spammy output with this change. Looks like this:

That is correct. it is still very spammy. I reduced the output where I could without redirecting all stderr from the library, which would start to mask errors.

We could suppress all stderr from the library and only provide it with a verbose flag (-v), if you'd prefer.

Let's try that, because it's still super spammy
