Tensorflow upgrade

Current Version: 1.4.1

Versions Tested:

  • 1.5.0
  • 1.6.0
  • 1.7.0
  • 1.8.0
    • Remarks: Upgrading to version 1.5.0-1.8.0 breaks no functionality and produces no error when running with Travis CI. Importing data models also do not seem to produce any problems.
  • 1.9.0 & 1.10.1
    • Errors encountered: An ImportError: dlopen: cannot load any more object with static TLS_ was thrown when trying to run the project.
    • Cause of error: This error seems to be thrown due to a wrong order of import statements, which is thought to be a bug as none of the breaking changes from v1.8.0 to 1.9.0 apply (source). On upgrading to 1.12.0, this issue no longer persists.
    • Travis CI log: 1.9.0, 1.10.1
  • 1.12.0 (latest version)
    • Remarks: Travis CI built successfully on this version of tensorflow. No functionality seems to be lost.
    • Tests performed:
      • Importing models from model zoo.
      • Importing a custom model downloaded from internet.
      • Exporting a model locally and then importing it again.
      • Making a simple model.
      • Importing / Exporting models of caffe and keras
