i still see old evrsion when would docker images get pupdated

[arielgamino]

I created a new Kernel and see the new version. You may need to create a new Kernel. If you created the Kernel before this merge, you will get what it was installed (fast.ai 0.7)

@jaideep11061982 In Settings panel on the right, next to Docker. Does it say Latest Available? If not, you have to select it. If it does, hit the refresh button in the console panel at the bottom of your screen.

@rosbo still unable to run the fast.ai on kernels. I am getting the module missing warning? Could you please suggest a way to get over this issue?
Thank You.
