Hmm, I have never seen this error before. It seems like other people have had problems with anaconda, it must be somehow related to its Python installation and version...

It's hard for me to fix this without being able to reproduce it.

I am also facing same issue... :(

is it some path issue ?

[srikanthtamilselvam]

I guess the requirement is to use tensorflow 1.0. version mismatch could lead to this problem

@zhang-jian @panwarnaveen9

have same issue before, solve by using pip3
$ pip3 install -e .

note: please remember to use python3 to run the code

[dennybritz]

please remember to use python3 to run the code

The code should also work with Python 2.7, it's tested with both versions. It seems like it can't find the module, but I have no idea why. You could try:

export PYHTONPATH=/path/to/seq2seq/directory

[zhang-jian]

After install tensorflow r1.0 (was r0.12), the problem is solved.

[jnuthong]

after upgrade tensorflow (1.0.1) do solve my problem

sudo pip install --upgrade tensorflow
