A rule for importing `requirements.txt` dependencies into Bazel.

This rule imports a `requirements.txt` file and generates a new
`requirements.bzl` file.  This is used via the `WORKSPACE` pattern:

```python
pip_repository(
    name = "foo",
    requirements = ":requirements.txt",
)
```

You can then reference imported dependencies from your `BUILD` file with:

```python
load("@foo//:requirements.bzl", "requirement")
py_library(
    name = "bar",
    ...
    deps = [
       "//my/other:dep",
       requirement("requests"),
       requirement("numpy"),
    ],
)
```

Or alternatively:
```python
load("@foo//:requirements.bzl", "all_requirements")
py_binary(
    name = "baz",
    ...
    deps = [
       ":foo",
    ] + all_requirements,
)
```

| <a id="pip_repository-download_only"></a>download_only |  Whether to use "pip download" instead of "pip wheel". Disables building wheels from source, but allows use of --platform, --python-version, --implementation, and --abi in --extra_pip_args to download wheels for a different platform from the host platform.   | Boolean | optional | <code>False</code> |
| <a id="pip_repository-enable_implicit_namespace_pkgs"></a>enable_implicit_namespace_pkgs |  If true, disables conversion of native namespace packages into pkg-util style namespace packages. When set all py_binary and py_test targets must specify either <code>legacy_create_init=False</code> or the global Bazel option <code>--incompatible_default_to_explicit_init_py</code> to prevent <code>__init__.py</code> being automatically generated in every directory.<br><br>This option is required to support some packages which cannot handle the conversion to pkg-util style.   | Boolean | optional | <code>False</code> |
| <a id="pip_repository-environment"></a>environment |  Environment variables to set in the pip subprocess. Can be used to set common variables such as <code>http_proxy</code>, <code>https_proxy</code> and <code>no_proxy</code> Note that pip is run with "--isolated" on the CLI so <code>PIP_&lt;VAR&gt;_&lt;NAME&gt;</code> style env vars are ignored, but env vars that control requests and urllib3 can be passed.   | <a href="https://bazel.build/rules/lib/dict">Dictionary: String -> String</a> | optional | <code>{}</code> |
| <a id="pip_repository-extra_pip_args"></a>extra_pip_args |  Extra arguments to pass on to pip. Must not contain spaces.   | List of strings | optional | <code>[]</code> |
| <a id="pip_repository-incompatible_generate_aliases"></a>incompatible_generate_aliases |  Allow generating aliases '@pip//&lt;pkg&gt;' -&gt; '@pip_&lt;pkg&gt;//:pkg'.   | Boolean | optional | <code>False</code> |
| <a id="pip_repository-isolated"></a>isolated |  Whether or not to pass the [--isolated](https://pip.pypa.io/en/stable/cli/pip/#cmdoption-isolated) flag to the underlying pip command. Alternatively, the <code>RULES_PYTHON_PIP_ISOLATED</code> environment variable can be used to control this flag.   | Boolean | optional | <code>True</code> |

| <a id="pip_repository-python_interpreter"></a>python_interpreter |  The python interpreter to use. This can either be an absolute path or the name of a binary found on the host's <code>PATH</code> environment variable. If no value is set <code>python3</code> is defaulted for Unix systems and <code>python.exe</code> for Windows.   | String | optional | <code>""</code> |
| <a id="pip_repository-python_interpreter_target"></a>python_interpreter_target |  If you are using a custom python interpreter built by another repository rule, use this attribute to specify its BUILD target. This allows pip_repository to invoke pip using the same interpreter as your toolchain. If set, takes precedence over python_interpreter. An example value: "@python3_x86_64-unknown-linux-gnu//:python".   | <a href="https://bazel.build/concepts/labels">Label</a> | optional | <code>None</code> |
| <a id="pip_repository-quiet"></a>quiet |  If True, suppress printing stdout and stderr output to the terminal.   | Boolean | optional | <code>True</code> |
| <a id="pip_repository-repo_mapping"></a>repo_mapping |  A dictionary from local repository name to global repository name. This allows controls over workspace dependency resolution for dependencies of this repository.&lt;p&gt;For example, an entry <code>"@foo": "@bar"</code> declares that, for any time this repository depends on <code>@foo</code> (such as a dependency on <code>@foo//some:target</code>, it should actually resolve that dependency within globally-declared <code>@bar</code> (<code>@bar//some:target</code>).   | <a href="https://bazel.build/rules/lib/dict">Dictionary: String -> String</a> | required |  |
| <a id="pip_repository-repo_prefix"></a>repo_prefix |  Prefix for the generated packages will be of the form <code>@&lt;prefix&gt;&lt;sanitized-package-name&gt;//...</code>   | String | optional | <code>""</code> |

| <a id="pip_repository-requirements_lock"></a>requirements_lock |  A fully resolved 'requirements.txt' pip requirement file containing the transitive set of your dependencies. If this file is passed instead of 'requirements' no resolve will take place and pip_repository will create individual repositories for each of your dependencies so that wheels are fetched/built only for the targets specified by 'build/run/test'.   | <a href="https://bazel.build/concepts/labels">Label</a> | optional | <code>None</code> |
