"attempted relative import above top-level package"

[Daniel Batten]

I've been getting this error repeatedly in attempting to run MFA. I've followed the readthedocs instructions to the letter. I've uninstalled, updated everything I can think to update, and reinstalled. Same issue.

I'm literate in this enough to get this far, but not to diagnose this issue on my own. Any help is greatly appreciate. 

Here's what I am getting. I have the same exact same output if I try to run it on my own data.

I think you're getting this because you're in the MFA directory.  As part of the installation, "mfa" should be available regardless of your current directory (if it's not, that's a separate issue).  If you're in that folder, it's going to get confused about the path to import from, and in this case, thinks that python files are top-level, when they're nested inside a package.  If you go back to your home directory and run the mfa commands from there, these errors shouldn't pop up.

That worked! Thank you. The way you phrased it makes perfect sense and got me to persist and correct something I was doing wrong attempting to run the commands at the home directory. It worked with both the LibriSpeech data and then with my own prepared data.
