for u,v in data:too many values to unpack (expected 2)

This error typically occurs when you are trying to unpack a sequence into too many variables. It seems like the `data` variable contains elements with more than two values, whereas you are trying to unpack them into only two variables (`u` and `v`). To fix this issue, you need to either change the unpacking statement or modify the `data` variable to contain elements with only two values.
Here's an example of how you can modify the code:
```python
for u, v, _ in data:
# Rest of your code
```
In this example, the extra value (assuming it is not needed) is ignored by using an underscore `_`. You can replace the underscore with an appropriate variable name if you need that value for further processing.
