tensorflow_probability: AttributeError: module 'tensorflow_probability.* has no attribute '*'

Question

I'm trying to reproduce a snippet of code I found on google colaboratory (here) and I have problems with the methods used (tfb.Shift and tfp.util.TransformedVariable) that I can't find in the documentation.

import numpy as np
import tensorflow.compat.v2 as tf
import tensorflow_probability as tfp
tfb = tfp.bijectors
tfd = tfp.distributions
tf.enable_v2_behavior()

constrain_positive = tfb.Shift(np.finfo(np.float64).tiny)(tfb.Exp())

amplitude_var = tfp.util.TransformedVariable(
    initial_value=1.,
    bijector=constrain_positive,
    name='amplitude',
    dtype=np.float64)

I get

AttributeError: module 'tensorflow_probability.python.bijectors' has no attribute 'Shift'

and

AttributeError: module 'tensorflow_probability.python.util' has no attribute 'TransformedVariable'

Could be a version issue?

I'm using tensorflow 2.0.0 and tensorflow-probability 0.8.0 and I see that in colab notebook is used @tf.function so I thought it used tensorflow 2.0.0 too.

What can I use instead?

Thank you very much

It seems there are lot of issues in tensorflow_probability's dependency management, unfortunately. I tried your code and got a slightly different import error.

You can try the following workarounds:

Use the latest release of tensorflow: pip install tensorflow==2.1.0rc2
Use CoLab, where tensorflow and tensorflow_probably are already installed by default: https://colab.sandbox.google.com/

Thanks but both using colab and updating the version I always get the same error

You should find the tensorflow_probability version that suit your tensorflow version, for me it's tensorflow 2.10 and tensorflow_probability 0.16.
