Return type:
         Tensor
sample_n(n)
  Generates n samples or n batches of samples if the distribution
  parameters are batched.

  Return type:
     *Tensor*

static set_default_validate_args(value)
  Sets whether validation is enabled or disabled.

  The default behavior mimics Python's "assert" statement:
  validation is on by default, but is disabled if Python is run in
  optimized mode (via "python -O"). Validation may be expensive,
  so you may want to disable it once a model is working.

  Parameters:
     **value** (*bool*) -- Whether to enable validation.

property stddev: Tensor
  Returns the standard deviation of the distribution.

property support: Optional[Any]
  Returns a "Constraint" object representing this distribution's
  support.

property variance: Tensor
  Returns the variance of the distribution.
