So I followed this tutorial for installation of Knet. The tests are OK, but first example does not work:

The link you provided contains Knet7 tutorial. On the other hand, you're using the Knet8. You can find tutorial for the latest version of Knet (Knet8) here

Thanks for answer. And is it possible to install the older version (Knet7) somehow? Because I am trying to run code, which looks like it uses the version 7.
