How to build Tensorflow from source with the ALREADY-installed TensorFlow Probability.

```
The TensorFlow Distributions library has moved to TensorFlow Probability (https://github.com/tensorflow/probability). You should update all references to use `tfp.distributions` instead of `tf.distributions`.
```

Hi @jiapei100 ,

Welcome to the TensorFlow Forum!

Tensorflow Distribution is now part of Tensorflow Probability module. You can access **Tensorflow Distribution** from installed `Tensorflow probability`

in your system as below:

```
import tensorflow_probability as tfp
tfd = tfp.distributions
```

and can find all itâ€™s usable APIs list by referring to the tfp.distributions APIs list.

Please refer to this link to build Tensorflow from source as per your system OS.
