Version and init files not packaged in the service repository

[marcindulak]

Describe the bug

The __init__.py file is empty and _version.py file missing in the service repository. The behavior depends on the location of the service export export_service.py script.

To Reproduce

Steps to reproduce the issue:

1. Clone the example mypackage

   git clone https://github.com/marcindulak/bentoml-missing-version-import

2. Install mypackage

   deactivate
   rm -rf /tmp/venv
   python3 -m venv /tmp/venv
   . /tmp/venv/bin/activate
   pip install ./bentoml-missing-version-import

3. Create BentoML service from the location where mypackage cannot be imported from the current working directory

   cd bentoml-missing-version-import
   mv export_service.py
   cd ..
   python export_service.py

4. The __init__.py and _version.py are missing:

   ls $(bentoml get Service:latest --print-location --quiet)/Service/mypackage
   # __init__.py  service.py

Expected behavior

The __init__.py and _version.py are created:

ls $(bentoml get Service:latest --print-location --quiet)/Service/mypackage
# __init__.py  service.py  _version.py

This is the case when export_service.py resides in the ./bentoml-missing-version-import directory.

cd bentoml-missing-version-import
python export_service.py

Thank you for the feedback @marcindulak - this issue should be fixed now in BentoML version 1.0, where user can specify arbitrary files to be included in the Bento, via a bentofile.yaml file. Here's an example build file:

service: "iris_classifier:svc"
description: "file: ./readme.md"
labels:
  foo: bar
  team: abc
include:
- "*.py"
- "*.json"
exclude: 
- "*.pyc"
