Unable to  build the pip package after building the package builder
Please see https://github.com/tensorflow/tensorflow/issues/63298, particularly https://github.com/tensorflow/tensorflow/issues/63298#issuecomment-1986141742 @vladbelit , i ran into that issue  mentioned in #63298 previously. In order to fix it i editted the "/home/administrator/tensorinstall/tensorflow/tensorflow/tools/pip_package/BUILD" file. 
i changed the following lines after which the package built succesfully

py_binary(
    name = "build_pip_package", # changed from "build_pip_package_py"
    srcs = ["build_pip_package.py"],
    main = "build_pip_package.py", > @vladbelit , i ran into that issue mentioned in #63298 previously. In order to fix it i editted the "/home/administrator/tensorinstall/tensorflow/tensorflow/tools/pip_package/BUILD" file. i changed the following lines after which the package built succesfully

### Current behavior?

After running the bazel package builder i am trying to build the pip package when i see the following error. Also important to note that i had to supply the --output-name and --project-name flags (since they are mandatory). This is not reflected in the guide to build tf from source. I also dont understand what headers need to be supplied. I see a command line option to supply headers though for the whl build.

### Standalone code to reproduce the issue

```shell
bazel build //tensorflow/tools/pip_package:build_pip_package

./bazel-bin/tensorflow/tools/pip_package/build_pip_package --output-name /tmp/tensorflow_pkg --project-name tensor
```


### Relevant log output

```shell
sudo ./bazel-bin/tensorflow/tools/pip_package/build_pip_package --output-name /tmp/tensorflow_pkg --project-name tensor
