Running out of GPU memory on first run dl1/dogscats

@stas to be honest I have been trying to install fastai 0.7 in all different ways possible for last 7 days and each time encountered a different issue when solve it another error would show up. and for me who am not a software engineer is really frustrating and time consuming. My latest error is when following Beginner Installation of FastAi 0.7 on Windows 10 Nvidia GPU 10xx steps, at the end when I run Jupyter notebook for lesso1-breeds is :
ImportError Traceback (most recent call last)

ImportError: DLL load failed: The specified module could not be found.

I re-installed torch, torchvision and torchtext one by one and repeated the whole steps mentioned above but I again received the same exact error. Really no clue what should I do :sweat::triumph:
