Tensorflow was previously installed. In 2018 Summer, a new piece of graphics card was installed on DB Server. Wei and Minh hence-force installed and configured '''tensorflow-gpu 1.9.0 for Python3.6''' for all users of DB Server.
===Using Tensorflow===
It is important to know that, on DB Server, Tensorflow-gpu 1.9.0 is installed for ''python3.6'', instead of either the default ''python3'' which is Python 3.5, or the default ''python'' which is Python 2.7 . In case that the system default ''python3'' might be changed, type to find out:
which python3
which python3.6
A quick test of whether tensorflow-gpu is working for ''python3.6'', type the following into a terminal:" python3.6 -c "import tensorflow as tf; sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))"
This will report back which CPU and GPU devices the tensorflow is using. If there is no information for the GPU device, there is something wrong.
