If you read the error message carefully, there is an answer.

The code indicated by the error is

if (0 <= pix) or (pix <= r1):

Here, 0 <= fix is what the error points to, or fix <= r1.

In conclusion, when debugging , do not look at the error message roughly, but make sure to interpret it well and carefully.
