train.py fails with best_model.ckpt not found

[hilmij]

Hi,
I am trying the example with Python 3.6.1 and TensorFlow 1.2.1 on Windows 10.

I am getting the following error when I run "python train.py ./data/train.csv.zip ./training_config.json".

CRITICAL:root:Saved model ./checkpoints_1501717661/model-2700 at step 2700

FileNotFoundError: [WinError 2] The system cannot find the file specified: './checkpoints_1501717661/model-2700' -> './trained_results_1501717661/best_model.ckpt'

I ran the train.py couple of times now. Same error. Please help me to solve this issue.

Thanks,
Hilmi.

Have you ever changed the original code files?If you have changed, maybe you can send your codes to me. I'll try to help you.

Thanks for the reply.
I did not change any files. Just trying to run as it is.

I tested the same with Ubuntu (Python 3.5.2, TensorFlow 1.2.1). Same result.

Please let me know if you need more info to figure this issue.

comment all the code after line 141, take a look at the checkpoint directory.

Then change the code after line 141 accordingly. Essentially you wanna save the best model to a file for prediction in future.

fix line 151:
from: os.rename(path, trained_dir + 'best_model.ckpt')
to: os.rename(path + '.ckpt', trained_dir + 'best_model.ckpt')
