Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/50321 Quantization team reported that when there are two empty tensors are replicated among ranks, the two empty tensors start to share storage after resizing. The root cause is unflatten_dense_tensor unflattened the empty tensor as view of flat tensor and thus share storage with other tensors. This PR is trying to avoid unflatten the empty tensor as view of flat tensor so that empty tensor will not share storage with other tensors.

C++ Frontend Tests
In this folder live the tests for PyTorch's C++ Frontend. They use the GoogleTest test framework.
CUDA Tests
To make a test runnable only on platforms with CUDA, you should suffix your
test with _CUDA, e.g.
TEST(MyTestSuite, MyTestCase_CUDA) { }
To make it runnable only on platforms with at least two CUDA machines, suffix
it with _MultiCUDA instead of _CUDA, e.g.
TEST(MyTestSuite, MyTestCase_MultiCUDA) { }
There is logic in main.cpp that detects the availability and number of CUDA
devices and supplies the appropriate negative filters to GoogleTest.
Integration Tests
Integration tests use the MNIST dataset. You must download it by running the following command from the PyTorch root folder:
$ python tools/download_mnist.py -d test/cpp/api/mnist
The required paths will be referenced as test/cpp/api/mnist/... in the test
code, so you must run the integration tests from the PyTorch root folder.
