Re-enable TestNamedTensor.test_big_tensor_repr (#29407)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/29407
Fixes https://github.com/pytorch/pytorch/issues/27753.
The bug was that random tensors print subtly differently. This causes
the "names=" tag to appear in slightly different places; sometimes it is
on the same line as the data, sometimes it is on different lines.
For this test, we wanted to know the following:
- printing a big named tensor's repr doesn't crash
- a big named tensor's repr shows the names
This PR changes the test to check those two things.
Test Plan: - run existing tests
