Should I see print(torch.__version__) dispaly 1.7.0 if nightly installed successfully?


No, you should see 1.7.0.devYYYYMMDD.
E.g. torch.linalg.norm is available in my local nightly installation using 1.7.0.dev20200830, which is approx. a month old by now.
I guess your nightly installation wasn’t working properly, so you might to reinstall it.
