Value Error with predictor line #311

Traceback (most recent call last):
File "model_test_mseed.py", line 16, in

File "/home/jneilson/anaconda3/envs/eqt/lib/python3.7/site-packages/EQTransformer/core/mseed_predictor.py", line 311, in mseed_predictor
predD, predP, predS = model.predict_generator(pred_generator)
ValueError: not enough values to unpack (expected 3, got 0)
Above is error that I am receiving, running a Ubuntu Linux install in a conda env. I am using custom data, but all is in correct format and works on a batch size of 100, but fails on any size above that. Any help is appreciated.
