Import `keras_cv` fails on current master

[smitlg]

Some parts of keras_cv depends on keras_nlp and tensorflow_text. The following errors pops up:

[/usr/local/lib/python3.10/dist-packages/keras_cv/models/feature_extractor/clip/clip_tokenizer.py](https://localhost:8080/#) in <module>
     14 import regex as re
     15 import tensorflow as tf
---> 16 import tensorflow_text as tf_text
     17 
     18 try:

ModuleNotFoundError: No module named 'tensorflow_text'

Fixing this error by pip install tensorflow_text, gives a new error:

[/usr/local/lib/python3.10/dist-packages/keras_cv/models/feature_extractor/clip/clip_tokenizer.py](https://localhost:8080/#) in <module>
    105 
    106 
--> 107 class CLIPTokenizer(BytePairTokenizer):
    108     def __init__(self, **kwargs):
    109         super().__init__(**kwargs)

NameError: name 'BytePairTokenizer' is not defined

This will be only fixed by installing keras_nlp or by the approach used in #2394

Hi,

Could you please let us know, what is the API which is causing error while importing.

Steps to reproduce(assuming you are on current master branch):

1. Uninstall both keras_nlp and tensorflow_text.
2. pip install .
3. Now, do import keras_cv.

Thanks for the input, I was able to reproduce the error

Same problem on Colab. Following this example: https://keras.io/examples/vision/yolov8/#creating-model
