``grad_outputs`` should be a sequence of length matching ``output`` containing the "vector" in vector-Jacobian product, usually the pre-computed gradients w.r.t. each of the outputs. If an output doesn't require_grad, then the gradient can be ``None``). ...
The formatMessage function uses vsprintf to format a string with variable arguments. va_start initializes the argument list, and va_end cleans it up. The formatted string is stored in the provided buffer. Note the fixed-size buffer (100 chars) which could overflow if the formatted string ...
