I am trying to move a large project to using Bazel, and I am starting small. I have found a small wrapper around pydantic in our project, and I am trying to "bazelify" that first.
The initial structure of the package was something like this:
pydantic_utils
+- __init__.py
+- some_module.py
+- some_other_module.py
+- subdir
+- one.py
+- tests
+- __init__.py
+- test_some_module.py
I added BUILD.bazel files to this structure and everything worked fine, my tests ran and passed. But then I thought, I'd put the tests into the root dir of our wrapper lib. So I moved the test_some_module one level up, moved the py_test target to the BUILD.bazel file in the root dir, modified the srcs of both targets not to include the other target's files:
load("@rules_python//python:defs.bzl", "py_library", "py_test")
load("@my_pip_install//:requirements.bzl", "requirement")
py_library(
name = "pydantic_utils",
srcs = glob(
["*.py"],
exclude = ["test_*.py"],
),
visibility = ["//visibility:public"],
deps = [
"//pydantic_utils/subdir",
requirement("pydantic"),
],
)
py_test(
name = "test_pydantic_utils_dp",
srcs = glob([
"test_*.py",
]),
main = "test_some_module.py",
deps = [
"//pydantic_utils",
requirement("pytest"),
],
)
But now I get an error, that pydantic cannot import TYPE_CHECKING for some reason.
...pydantic_utils/test_some_module.py", line 2, in <module>
from typing import Any
...
File "pydantic/__init__.py", line 2, in init pydantic.__init__
from .models import (
File "pydantic/dataclasses.py", line 1, in init pydantic.dataclasses
import re
ImportError: cannot import name TYPE_CHECKING
It is a very vague question, but I have no idea how to begin to diagnose it. Can anyone help me?
