Nmt: OsError: Tensorflow version must >= 1.4.0.dev

[paleuribe]

When I run the first example (Vietnamese-English), it appears the message "OsError: Tensorflow version must >= 1.4.0.dev". I have updated Tensorflow, but the last version still is 1.3.0 . There is a 1.4.0-rc version (https://github.com/tensorflow/tensorflow/releases/tag/v1.4.0-rc0), but is a pre-release. How can I fix this?

simple hack :
change the version number to 1.0.0.dev or latest 1.x version u have in nmt/utils/misc_utils.py

original :
def check_tensorflow_version():
min_tf_version = "1.4.0-dev"
if tf.__version__ < min_tf_version:
raise EnvironmentError("Tensorflow version must >= %s" % min_tf_version)

changed:
def check_tensorflow_version():
min_tf_version = "1.0.0-dev"
if tf.__version__ < min_tf_version:
raise EnvironmentError("Tensorflow version must >= %s" % min_tf_version)

also make sure to install tensorflow-nightly
pip install tf-nightly
https://github.com/tensorflow/tensorflow/#installation

worked for me....!

@paleuribe @tkngoutham You need to install tf-nightly if you want to use the master branch.

Otherwise, you can use the tf-1.2 branch for released versions.

Thanks, @tkngoutham @oahziur, but I have installed the last version of Tensorflow (1.3.0), and tf-nightly. @tkngoutham , how can I make that change?

[tkngoutham]

@paleuribe the function check_tensorflow_version is in file nmt/utils/misc_utils.py
@oahziur I did as u said and it worked for me...!

@oahziur I uninstalled and reinstalled tf-nightly, and now it works, thanks!
