Hi, I am getting the file not found error whenever I run t2t_problem.generate_data(DATA_DIR, TMP_DIR). Download of the data set was successful to TMP_DIR. ...

Environment information

Python 3.7.7 tensor2tensor 1.15.7

OS: <Windows 10>

$ pip freeze | grep tensor

# Steps to reproduce:
...

from tensor2tensor.utils import registry from tensor2tensor import models

registry.list_models()

from tensor2tensor import problems import json

from tensor2tensor.utils.trainer_lib import create_hparams

Print all T2T problems to console

problems.available()

TRAIN_DIR = '~/translator/model_files' TMP_DIR = 'C:/MachineLearning/Speech_Recognition/temp/' DATA_DIR = 'C:/MachineLearning/Speech_Recognition/speech_data/'

t2t_problem = problems.problem(PROBLEM) t2t_problem.generate_data(DATA_DIR, TMP_DIR)
