I was running License Plate Detection notebook in colab and after running this cell:
`# Exporting the freezed training .pb file
This model will be used later on to perform inference
import re
import numpy as np
output_directory = './fine_tuned_model'
lst = os.listdir(model_dir)
lst = [l for l in lst if 'model.ckpt-' in l and '.meta' in l]
steps=np.array([int(re.findall('\d+', l)[0]) for l in lst])
last_model = lst[steps.argmax()].replace('.meta', '')
`ValueError Traceback (most recent call last)

10 lst = [l for l in lst if 'model.ckpt-' in l and '.meta' in l]

Did your model training start? I was able to reproduce this error when I deleted all the files from /content/models/research/training/, which means the model was not saved

Got this error:
`ValueError Traceback (most recent call last) in ()

What should I do?
