导入错误：没有名为 tensorflow_transform.beam 的模块

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)

    return dill.load_session(file_path)

    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")
