Question about PyTorch license or SPDX tag

Hello, I would like to ask a question about the license that PyTorch is released under or PyTorch’s SPDX tag. I need this info for an internal open source contribution approval. It seems that both Tensorflow and MxNET use Apache License 2.0. Caffe is released under BSD 2-Clause license. However, from PyTorch license page on github, I only can find copyright info, but no license name there. Does someone know the PyTorch license or SPDX tag info? Thanks.

I’m not a lawyer, but the LICENSE file looks like 3-clause-BSD to me. Note that the license text seems to be applicable to all the copyrighted files that are listed above and was present before the caffe2 merge.

Best regards
