If you create a new issue, please provide the following information:

  1. Which program causes the problem
  • Custom TF operation
  • C++ test program
  • Python prototype
  1. Versions
  • TensorFlow version = 2.1.0
  • Python version = 3.7.7
  • C++ compiler = 11.0.3
  • Operating system = macOS Catalina 10.15.4
  1. Issue

  • Which result/error did you get?

    AttributeError: module 'tensorflow' has no attribute 'Session'

  • If you think the result is wrong - what result did you expect instead?

     Mini example:
 Label string:  [1 0 3]
 Char string: "ba"

 # ... remainder of example omitted...

  • How to reproduce the issue?

    Just follow the setup documentation with the latest versions of TensorFlow, Python, and Pip. It doesn't work.

  • Provide all necessary data, at least these files: chars.txt, wordChars.txt, corpus.txt, gt_X.txt, mat_X.csv

    N/A

Follow up: even dropping back to TensorFlow 1, I get the following when running the test:

tensorflow.python.framework.errors_impl.NotFoundError: dlopen(cpp/proj/TFWordBeamSearch.so, 6): Library not loaded: @rpath/libtensorflow_framework.2.dylib

Did you compile the C++ test program or the TF custom op? Because your issue report is ambiguous.
I guess you want to compile for TF. The "AttributeError: module 'tensorflow' has no attribute 'Session'" is due to TF 2, which I do not support.
The error reported in your second post seems to be some problem with TF in combination with Mac!? I don't have a Mac to test it, so I can't figure out what the problem is. However, when you search for the text "Library not loaded: @rpath/libtensorflow_framework.2.dylib" in Google you get a lot of hints how other people fixed it.

At some point I will add a Python/Numpy interface to the C++ code to get rid of all those TensorFlow dependencies. But I don't know when I will have the time to do this.

Hi Harald,

I am unable to compile TFWordBeamSearch.so on MacOS Catalina 10.15.2. Getting error as below:

ld: library not found for -l:libtensorflow_framework.1.dylib
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any idea what could be wrong here. I tried adding additional MacOS flag -undefined dynamic_lookup in the g++ command that prepares the .so file. Please help.

I tried setting LIBRARY_PATH, CPPFLAGS, LDFLAGS, LD_LIBRARY_PATH but no luck yet. Anticipating best answer from your side. Thanks and have a good day. Stay safe.
