I installed TensorFlow on my MacBook Pro 10.12.5 from source code by steps described here. https://www.tensorflow.org/install/install_sources
TensorFlow itself works wel
What version of Tensorflow are you running? Older versions don't include Tensorboard.
If you do have a newer version, I see you are using OSX, which apparently caused some problems for other people: https://github.com/tensorflow/tensorflow/issues/2115 Check this page to fix it!
As a MacPorts user, I'm used to running things from out of the path /opt/local/bin. When you install a python package via MacPorts, that's where the executables go --- even if they're just symbolic links to files to a main python repository in /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/
pip installs things into the latter directory, but apparently does NOT add the symbolic link to /opt/local/bin
This has never been an issue (or even come up) for me before, because I've only used pip to install (non-executable) packages which load from within python. In conclusion, there is a /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/tensorboard
This is a pip / MacPorts-SOP mismatch / user error*, and nothing to do with tensorboard in particular. Please close this issue. Thanks for your help.
