 | python_requires |  A string specifying what other distributions need to be installed when this one is. See the section on [Declaring required dependency](https://setuptools.readthedocs.io/en/latest/userguide/dependency_management.html#declaring-dependencies) for details and examples of the format of this argument.   | String | optional | "" |
 | python_tag |  Supported Python version(s), eg <code>py3</code>, <code>cp35.cp36</code>, etc   | String | optional | "py3" |

 | stamp |  Whether to encode build information into the wheel. Possible values:<br><br>- <code>stamp = 1</code>: Always stamp the build information into the wheel, even in [--nostamp](https://docs.bazel.build/versions/main/user-manual.html#flag--stamp) builds. This setting should be avoided, since it potentially kills remote caching for the target and any downstream actions that depend on it.<br><br>- <code>stamp = 0</code>: Always replace build information by constant values. This gives good build result caching.<br><br>- <code>stamp = -1</code>: Embedding of build information is controlled by the [--[no]stamp](https://docs.bazel.build/versions/main/user-manual.html#flag--stamp) flag.<br><br>Stamped targets are not rebuilt unless their dependencies change.   | Integer | optional | -1 |
 | strip_path_prefixes |  path prefixes to strip from files added to the generated package   | List of strings | optional | [] |
 | version |  Version number of the package. Note that this attribute supports stamp format strings. Eg <code>1.2.3-{BUILD_TIMESTAMP}</code>   | String | required |  |
