Fatal: no such path error within git blame subprocesss

[mhyeonsoo]

Hello,

Thanks for the nice library.
I am trying to run training script for my repo., but facing error starting with 'Fatal: no such path [ ]'
And training finishes with 0 positive cases which returns feature extraction error during prediction.
When I run predict with the model trained, it returns the error 'feature extraction error', and it seems like all the labels are set to 0.

I found that this case does not happen everytime. for some repos. it works well, but for some doesn't.
Is there any reason for this?

Thanks,
