Each expert calculated **independently**, because calculation time is too big, so, depends on how many experts you need to

```python
processed_expert = process_single_expert(experts[0])
```

  
**and then press Calculate, when finished do**

```python
processed_expert = process_single_expert(experts[1])
```

  
And so on

When all experts are calculated you need to scroll down, to next Cell, and combine results into single JSON
