Hello,

I am trying to follow the tutorial in NMT with the toy data. I follow the instructions but when I try to train the model I get the following error:

Traceback (most recent call last):
  File "/usr/local/tensorflow-1.1/lib/python2.7/runpy.py", line 174, in _run_module_as_main
    "__main__", fname, loader, pkg_name)

I think it may be related with how I run the command in the console:

[ijauregi@phoenix22 seq2seq]$ python -m bin.train --config_paths="./example_configs/nmt_small.yml, ./example_configs/train_seq2seq.yml, ./example_configs/text_metrics_bpe.yml" --model_params "vocab_source:$VOCAB_SOURCE vocab_target:$VOCAB_TARGET" --input_pipeline_train "class:ParallelTextInputPipeline params:source_files:-$TRAIN_SOURCES target_files:-$TRAIN_TARGETS" --input_pipeline_dev "class:ParallelTextInputPipeline params:source_files:-$DEV_SOURCES target_files:-$DEV_TARGETS" --batch_size 32 --train_steps $TRAIN_STEPS --output_dir $MODEL_DIR

Am I writing something wrong? Thank you very much

Solved. I wrote the command in a '.sh' file and now it works well.
