My build shows it is built with pytorch, so there is no need for me to build Pytorch again from source?


You don’t need to build PyTorch from source, but sometimes the binaries you download via conda or pypi don’t have some desired feature enabled, then the only way to get them working is building everything from source and making sure the build options match your needs.

Let’s say pytorch is built with mkldnn, we anyway have to explicitly use “to_mkldnn()” method to make use of mkldnn operations, right?


Yes.
