prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  No module named 'elasticdl.python.elasticdl.layers' on master
  ```
  Traceback (most recent call last):
    File "/usr/local/lib/python3.7/runpy.py", line 193, in _run_module_as_main
      "__main__", mod_spec)
    File "/usr/local/lib/python3.7/runpy.py", line 85, in _run_code
      exec(code, run_globals)
    File "/elasticdl/python/master/main.py", line 28, in <module>
      from elasticdl.python.elasticdl.layers.embedding import Embedding
  ModuleNotFoundError: No module named 'elasticdl.python.elasticdl.layers'
  ```
  
  Seems `layers` directory is not installed to `/usr/local/lib/python3.7/site-packages/elasticdl-develop-py3.7.egg/elasticdl/python/elasticdl` after running `python setup.py install`
  
  Steps to reproduce:
  
  1. In a Python Docker container, clone ElasticDL and run `python setup.py install`
  1. remove the cloned source
  1. execute a demo job by: `elasticdl train ...`
