Feature File Path and Database File paths not being written after training

Using current version of RVC (pulled the latest to verify just before writing this report),

When Training, it generates the weights but does not generate the feature file or database file required for inference.
*** No Index File is created**

I'm using an Ubuntu system, I installed RVC via a venv to ensure no conflicts. This is the tail end of the training excerpt and crash log:

INFO:model3:Saving model and optimizer state at epoch 200 to ./logs/model3/G_200.pth
INFO:model3:Saving model and optimizer state at epoch 200 to ./logs/model3/D_200.pth
INFO:model3:====> Epoch: 200
INFO:model3:Training is done. The program is closed.
INFO:model3:saving final ckpt:Success.

Comienza reproduciendo el flujo de entrenamiento de Ubuntu e inspecciona train_nsf_sim_cache_sid_load_pretrain.py alrededor de main() e infer-web.py alrededor de train1key() en la línea 844. Rastrea las rutas generadas para los archivos de feature, índice y base de datos junto con la ProcessExitedException registrada y el error de concatenate. Se considera terminado cuando el entrenamiento produzca los archivos requeridos y el modelo resultante pueda continuar con la inferencia sin este fallo.
