Tensorflow Compile Runs For A Long Time
Unfortunately, some programs can take a long time to compile. A couple of hours of compilation is not strange for tensorflow on your setup.
There are reports of it taking 50 minutes on a considerably faster machine
A solution to this problem is to use pre-compiled binaries that are available with pip, instructions can be found here: https://www.tensorflow.org/install/pip.html
Basically you can do this:
pip install tensorflow
If you require a specific older version, like 1.15, you can do this:
pip install tensorflow==1.15
For gpu support you add -gpu
to the package name, like this:
pip install tensorflow-gpu
And:
pip install tensorflow-gpu==1.15
