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

Question

向 GCP 提交 Dataflow 作业时，出现此错误：

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
    value = func(*args)
  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

我的假设是预先安装了 tensorflow-transform 和 apache-beam 等要求，并且它在几个月前就可以使用了。

这是解决方案，将其放在此处供面临相同问题的人使用。

假设文件包含所有梁步骤，您需要在与您正在运行的文件相同的目录中包含 setup.py 文件。

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(),
              )

在我有的python文件中

options = PipelineOptions()

必须改为：

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