Bazel changes filename of .so, making it un-importable

I'm using bazel to build a simple python script with

py_binary(
   name = "test",
   srcs = ["test.py"],
   data = ["bpy.so"],
   python_version = 'PY3',
)

As seen, I'm hoping to be able to import bpy, a library I built according to https://wiki.blender.org/wiki/Building_Blender/Linux/Ubuntu.

I was able to locate it after bazel build, but its name is no longer bpy.so, but bpy__py_binary_resource_test__h6PPJs.so. So now when I tried to import it, I get

ImportError: dynamic module does not define init function (initbpy__py_binary_resource_test__h6PPJs)

My Questions

(1) Is data = ["bpy.so"] the correct way to make sure I can import bpy on a remote machine after blaze build? I always feel weird to use the keyword data for a lib...

(2) If this is the correct way, how do I import it after the build, since the filename has changed and the init function inside will no longer be reachable (as told by the error message).

Solution

  • For future readers, I was able to solve this problem by not bazel build'ing it into a .par.
