I’m not sure if this really belongs here, but I can’t find anything else online.
When trying to download cuDNN I get the following error
$ wget "http://platform.ai/files/cudnn.tgz" -O "cudnn.tgz"
--2017-05-03 21:19:22-- http://platform.ai/files/cudnn.tgz
Resolving platform.ai (platform.ai)... failed: Name or service not known.
wget: unable to resolve host address ‘platform.ai’
Now I am most definitely connected to the internet, and I also think my DNS is working properly, since I’m writing this on the same machine I tired to download the file. It also doesn’t work if I try to download via a browser, saying it can’t resolve the name.
I also tried dig -t A platform.ai +short but not getting any response (works for other domains).
Edit: as a side question, why are the .tgz and .sh installers recommended instead of the nvidia provided .deb packages?
In the youtube videos, at least in the lesson one video: https://youtu.be/Th_ckFbc6bI?t=49m27s. The platform.ai web address appeared in both the browser and your command line demo. An on-screen callout would be greatly helpful for first time course taker.
@jeremy Could you set a CNAME entry on platform.ai to be an alias of files.fast.ai? This way, the old domain will still be supported and does not break exisiting documentation, while you won’t need to care about further DNS settings anymore.
Maybe a 301 Moved Permanently redirect for people / search engines to be able to adjust links when stumbling upon old documentation? Broken links are so frustrating…
I just happened to recently start with lesson 1, where you are downloading the files from http://platform.ai/files, as xlaokunxu mentioned. I wrote a little script which did the download for me. A couple days later, when I tried to execute it on a GPU enabled machine, I panicked a bit when the download failed, not being sure what was happening to your project.
Anyway, thanks for all the effort you put in here, and good luck with the new company! I’ll also report it here when I find platform.ai links in your lessons.
Here is the error message from lesson1 notebook:
