If you're using [mypy](http://mypy-lang.org/), you'll need to turn on
|
|
[namespace packages](https://mypy.readthedocs.io/en/stable/command_line.html#cmdoption-mypy-namespace-packages),
|
|
otherwise `mypy` won't be able to run correctly.
|
|
|
|
To turn on namespace packages, do one of the following:
|
|
|
|
Add the following to your project configuration file:
|
|
|
|
```toml
|
|
[tool.mypy]
|
|
namespace_packages = true
|
|
```
|
|
|
|
Or, use a command-line switch:
|
|
|
|
```shell
|
|
mypy --namespace-packages
|
|
```
