Are you sure your installed it right ? No messing around virtual environment ? Proper TensorFlow version ?

#3

yep, I’m 100% sure, I use a virtual environment, for the tensorflow version = 1.12.0

#4

Do you mind retrying 100% from scratch, with a new virtualenv, and copy/pasting exactly all you do?

#5

yap, I have re-installed for 3 time

#6

Check if you’re not mixing Python 2 and 3. The pip install log looks like Python 3, but bin/run-ldc93s1.sh runs “python”, so depending on your system setup that could be picking up Python 2. A virtualenv created with -p python3 should prevent that from happening though.
