Unable to Adjust Alpha Range for Privacy Bound in Latest Version of Opacus #670

Closed zedoul closed 2 months ago

zedoul commented 2 months ago

UserWarning: Optimal order is the largest alpha. Please consider expanding the range of alphas to get a tighter privacy bound.

According to the official Opacus documentation, the privacy_engine.make_private_with_epsilon function should allow to specify a range of alphas to obtain tighter privacy bounds as follows:

You can pass your own alphas by passing alphas=custom_alphas when calling privacy_engine.make_private_with_epsilon

However, it seems that this functionality is no longer available in the latest version.

Thanks for the pointer! You are right, the functionality is removed now. We will update the website accordingly.
