ImportError: No module named tensorflow_transform.beam

Question

When submitting a Dataflow job to GCP I get this error:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/dataflow_worker/batchworker.py", line 766, in run
    self._load_main_session(self.local_staging_directory)
  File "/usr/local/lib/python2.7/dist-packages/dataflow_worker/batchworker.py", line 482, in _load_main_session
    pickler.load_session(session_file)
  File "/usr/local/lib/python2.7/dist-packages/apache_beam/internal/pickler.py", line 266, in load_session
    return dill.load_session(file_path)
  File "/usr/local/lib/python2.7/dist-packages/dill/_dill.py", line 402, in load_session
    module = unpickler.load()
  File "/usr/lib/python2.7/pickle.py", line 864, in load
    dispatch[key](self)
  File "/usr/lib/python2.7/pickle.py", line 1139, in load_reduce

  File "/usr/local/lib/python2.7/dist-packages/dill/_dill.py", line 818, in _import_module
    return __import__(import_name)
ImportError: No module named tensorflow_transform

My assumption is that requirements such as tensorflow-transform and apache-beam are pre-installed and it used to work a few months ago.

Here is the solution, putting it up here for people who are facing the same issue.

You need to have setup.py file in the same directory as the file you are running, assuming that the file has all the beam steps.

import setuptools

setuptools.setup(
              name='whatever-name',
              version='0.0.1',
              install_requires=[
                  'apache-beam==2.10.0',
                  'tensorflow-transform==0.12.0'
                  ],
              packages=setuptools.find_packages(),
              )

In the python file I had

options = PipelineOptions()

which had to be changed to:

options = PipelineOptions(setup_file="./setup.py")
