)[source]¶

Return a tensor initialized from the truncated normal distribution.

\[\text{out} \sim \mathcal{TN}(\mu, \sigma^{2}, \mu - 2\sigma, \mu + 2\sigma) \]

Parameters:

• shape (Sequence[Union[int, dragon.Tensor]]) – The shape of the tensor.
• mean (number, optional, default=0) – The value to \(\mu\).
• stddev (number, optional, default=1) – The value to \(\sigma\).
• dtype (str, optional) – The optional data type.
• seed (int, optional) – The optional random seed.
• name (str, optional) – The operation name.

Returns:

dragon.Tensor – The output tensor.
