Training with continue and fork mode terminated due to unhandled system error

Bug Description

Hello, I've been trying to train the sota/2019 pre-trained dev-clean transformer model for 1 more epoch using flashlight's train continue mode. However, it fails to start training as the pre-trained models from wav2letter are not compatible with flashlight. I then installed wav2letter v0.2 to try retraining the pre-trained models using train continue but it fails and shows this error:

I0401 12:50:50.303958 29472 Train.cpp:80] Parsing command line flags

I tried using train fork and still the error persists. This error does not occur using train alone.

Reproduction Steps

This is what I ran:

wav2letter/build/Train continue /mnt/d/198 --minloglevel=0 --logtostderr=1 --rndv_filepath=

Is there other way to try to train the pretrained models for just 1 epoch?
