DeepLearningFlappyBird Checkpoint not found

trafficstars

I tried to run this and this showed on the terminal (on ubuntu):

W tensorflow/core/kernels/io.cc:228] Not found: Unsuccessful TensorSliceReader constructor: Failed to find any matching files for bird-dqn-30000

So I went to the "saved_networks" folder, and "bird-dqn-30000" was there.

Inside the checkpoint file, the content was:

model_checkpoint_path: "bird-dqn-30000"
all_model_checkpoint_paths: "bird-dqn-10000"
all_model_checkpoint_paths: "bird-dqn-20000"
all_model_checkpoint_paths: "bird-dqn-30000"

I changed the first line to:

model_checkpoint_path: "saved_networks/bird-dqn-30000"
all_model_checkpoint_paths: "bird-dqn-10000"
all_model_checkpoint_paths: "bird-dqn-20000"
all_model_checkpoint_paths: "bird-dqn-30000"

Worked fine.

I don't know if this is a real issue, or just something messy with my system. Just want to let you know.

Hello @LecJackS , What's your TensorFlow version?

Mar 22 '16 00:03 yenchenlin

It was 0.6.0

Upgraded to 0.7.1

Worked perfectly as default.

Sorry about that :shame:

Mar 22 '16 00:03 LecJackS

Don't be haha :smile: I will close this issue.

Thanks!

Mar 22 '16 01:03 yenchenlin

Hi guys, I have exactly same trouble. My TF version is 0.7.1. Prepending saved_networks/ helped as @LecJackS suggested.

Would @yenchenlin1994 consider updating the info?

Regards :)

Hello @petrbel , You mean even if your TF version is 0.7.1 you still need to Prepend saved_networks/ to make it work?

Mar 27 '16 09:03 yenchenlin

@yenchenlin1994 Exactly. I run Ubuntu 15.04

Mar 27 '16 11:03 petrbel

hmm ... its's strange. I can't reproduce the issue.

Hello @LecJackS , would you please delete this project on your computer and clone it again, and check if it can run? (with default setting)

I tried it once again. This is the log without any modification:

Thx @petrbel , Although I can't reproduce it, I would like to fix it.

May you enter the Python shell and type

import tensorflow
tensorflow.__version__

?

Mar 27 '16 16:03 yenchenlin

Sure!

>>> import tensorflow
>>> tensorflow.__version__
'0.7.1'

Thanks @petrbel , sorry I can't find out what's the issue, therefore I add a section in README about this. I'll try to figure out if there are more reports like this.

Thanks @yenchenlin1994 , I think it's ok this way. Everybody can search the issue and try it :) I'll ask some other guys to try it.
