torch.Tensor.const_data_ptr

Tensor.const_data_ptr() → int

Returns the address of the first element of self tensor.

Unlike data_ptr(), this is guaranteed to be a read-only access that will not trigger copy-on-write materialization. For regular (non-COW) tensors, the return value is identical to data_ptr().

Warning

The returned pointer must not be used to mutate the tensor data. Use data_ptr() when write access is needed.
