Error use (how can i do plz?) thks about katana HOT 1 OPEN

Hi, in the future, please wrap any output in three backticks like this:

```
Your output goes here
```

Next, please include a description of your problem. What were you trying to do? What command did you run? What kind of computer/operating system are you running on? How did you install katana? There's no way for us to guess these types of things. Every computer is different, and the problem could simply be a special case due to your specific environment. These are all things that will help the debugging process.

Regarding the traceback you posted, can you tell me how you installed katana? Obviously, there are depenencies missing which shouldn't happen if it was installed according to the documentation.

from katana.
