Update requirements.txt file about mc_gradients

Yes, unfortunately the DoubleMaxwell Distribution is not present in the older versions of TFP, which are compatible with TF1.

Will close this for now, but proper fix will be more involved.

I just pushed a change which fixed it for me. Can you confirm this works for you now?

Thanks!

python -m monte_carlo_gradients.gradient_estimators_test still gives me an error.

AttributeError: module 'tensorflow_probability.python.distributions' has no attribute 'DoublesidedMaxwell'

But the main works, python -m monte_carlo_gradients.main.

Thanks!

@jacarvalho FYI I now fixed the tests too. This entails you can use the measure valued gradient estimation too, and thus everything should be available.

Great! thanks!
