I've managed to get TensorFlow (GPU) working in Python 3.5.2, but when I try to launch tensorboard from the command prompt, I get this error:

Error importing tensorflow. Unless you are using bazel,
you should not try to import tensorflow from its source directory;
please exit the tensorflow source tree, and relaunch your python interpreter
from there.
Is there a way to launch tensorboard from Python directly, or should I try to fix tensorboard in CMD? Thanks in advance.
EDIT:
I ran the following script that determined that TensorFlow was installed correctly:
