 ### Possible problems
 
 If you encounter crashes when running the TF-using application, or it errors out with `Not found: No session factory registered for the given session options`, try the change to `tensorflow/BUILD` suggested in https://github.com/tradr-project/tensorflow_ros_cpp/issues/9#issuecomment-604692643, clean the bazel workspace, and build it again.

+Tensorflow 1.15+ is not compatible with ROS Indigo. You will get linking errors when using the library. Please use TF 1.14 or older on Indigo.
