ImportError: No module named 'tensorflow_backend'

[axelreichwein]

I'm trying to run train.py. and I get this error:

Traceback (most recent call last):
  File "C:\Users\Axel\git\RelationPrediction\code\train.py", line 5, in <module>

    from optimization.optimize import build_tensorflow
  File "C:\Users\Axel\git\RelationPrediction\code\optimization\optimize.py", lin
e 1, in <module>
    import tensorflow_backend.algorithms as tensorflow_algorithms
ImportError: No module named 'tensorflow_backend'

I don't know which package I should install to resolve this module import error. Below is the list of packages in my python environment. I have tensorflow and keras installed.

[axelreichwein]

I found the missing package in the git repo. Sorry, I’m not so familiar with Python.

[guotong1988]

Same question, Thanks.

[pushpankar]

I am getting the same error. How you guys solved it?

[axelreichwein]

The referenced modules are under main/optimization. You need to add them to your PYTHONPATH.

[pushpankar]

Thanks @axelreichwein I solved it using relative path.

[YijingZhang]

You can add the following code in optimize.py to let the project search modules in the relative directory.

import sys sys.path.append(r"the definite path of the optimization folder")

[zhangzy6]

I get the same error.I try above methods, but I also solve it? @axelreichwein
