I surprisingly found that I have both PyTorch 0.4.1 and PyTorch 1.0 preview in my Anaconda.I thougth the PyTorch1.0 has overwritten the 0.4.1 version.But it didn’t. Inspired by toggling bewteen Python2.x and Python3.x in PyCharm.I’m wondering if I could toggle the different version of PyTorch just like switching Python.If it really works, I can enjoy the new features and at the same time I can learn others’ code writting in previous versions.Anyone can give me an answer!thanks!
