week 4 course 1

model is running but the grader output gives

> Cell #UNQ\_C4. Can’t compile the student’s code. Error: RuntimeError(“Expected object of scalar type Float but got scalar type Long for sequence element 1 in sequence argument at position #1 ‘tensors’”,)

i tried making ALL tensors in the cell to float but the problem remains BUILDUING CONDITIONAL GAN

This is a known problem that is caused by the grader using an older version of `torch`. [Here’s a thread](https://community.deeplearning.ai/t/cant-compile-the-students-code-runtimeerror/289318/7) which discusses in more detail.

Also note that the Conditional GAN is not Week 1, but Week 4. I’ll edit the title to change the tag for you.
