I get the following error message following the instructions in the Sequence to Sequence tutorial:
https://www.tensorflow.org/tutorials/seq2seq
When i started
python translate.py --data-dir [your data directory]
I end up with the following error when the script creates the layers:
AttributeError: 'NoneType' object has no attribute 'update'
(Full stack trace below)
System Information:
- macOS 10.12.5
- Python 3.5.3
- Tensorflow 1.2.0
- Tensorflow installed via pip (9.0.1) within conda (4.3.21)
In addition, WMT data is uploaded and processed. I downloaded data from English to French, as indicated in the tutorial.
Any help would be greatly appreciated.
