NoneType object Error when generating about rnn.wgan HOT 8 CLOSED

1. About the NoneType bug- are you sure you are using the correct version of TF? This repository may not work with other versions of TF.
2. As with all neural networks, this model trains much faster on GPU than on CPU. If you don't have a GPU it will take a long time to train the network.

If you have further questions you can email me.

Dear Ofir,

My Tensorflow version is 1.1 as your code required. I also tried on other version of TF (with a little modification) but it still got the same error.
About the second problem, I will try training on GPU later. Thank you.

I'm not exactly sure why you are receiving this error but I think it could be because your checkpoint directory is incorrect.
Maybe it should be:
python generate.py --CKPT_PATH=./logs/Generator_RNN_CL_VL_TH-Discriminator_RNN-50-10-512-512-1509799522.05-/checkpoint --DISC_GRU_LAYERS=2 --GEN_GRU_LAYERS=2

(Notice the period I put at the beginning of the directory)

I tried that path but it still got the same error @@.

Ofir, in your code, file generate.py, lines 20:
_, inference_op = Generator(BATCH_SIZE, charmap_len, seq_len=SEQ_LEN)
You just initialize the Generator with 3 first parameter, so the rnn_cell parameter is still None, is that okay?

Yup the code is fine.

Make sure that this directory actually exists
./logs/Generator_RNN_CL_VL_TH-Discriminator_RNN-50-10-512-512-1509799522.05-/checkpoint

I think that the problem is that the directory you gave the program is wrong.

same issue in #10 . I'm also not familiar with the code, but after some code reading, I found maybe the problem is in the line L20 of generate.py, where you should pass the correct parameter rnn_cell to the function call:
_, inference_op = Generator(BATCH_SIZE, charmap_len, seq_len=SEQ_LEN, rnn_cell=RNN_CELL) disc_fake = Discriminator(inference_op, charmap_len, SEQ_LEN, reuse=False, rnn_cell=RNN_CELL)

But this single fix won't let the code work. After some fail and trial, I found the line L238 in single_length_train.py has changed the ckp data path by arbitrarily adding a /ckp suffix, which breaks the readme guide.
so, instead of using path like:
--CKPT_PATH=./logs/Generator_RNN_CL_VL_TH-Discriminator_RNN-50-10-512-512-1516543503.49-/checkpoint
you should type something like:
--CKPT_PATH=./logs/Generator_RNN_CL_VL_TH-Discriminator_RNN-50-10-512-512-1516543503.49-/checkpoint/seq-5/ckp

I'm so sorry to point out that maybe the merge from NickShahML breaks some code, which the authors may not intend to? :)

Thanks for reporting this. We've reverted the code back to what it was when we published the paper. We believe this issue should be solved, as that code was thoroughly tested by us.

If this issue persists, please post here.
