Description

When i invoke the generate function twice with different idx,it appears the fault described as "RuntimeError: The expanded size of the tensor (181) must match the existing size (168) at non-singleton dimension 3. Target sizes: [1, 32, 68, 181]. Tensor sizes: [1, 1, 68, 168]"

should i reset the model' arguements or reload the model?

Research direction

Start by locating the generate function and reproduce two calls with different idx values, recording the tensor shapes from the reported error. Check whether the second call succeeds without reloading or resetting the model; done means the repeated-call behavior is fixed or the required reset or reload behavior is documented.
