根据错误信息,看起来在使用`w_data[w_data['波束场景No'] == cross_data['波束场景No'][0]]`时出现了`KeyError: '波束场景No'`错误。这个错误通常表示在`w_data` DataFrame中不存在名为'波束场景No'的列。
要决这个问题,你可以先检查一下`w_data` DataFrame的列是否与你使用的列名完全配。请确保列名的拼写和大小写与数据框中的实际列名一致。
你可以使用`columns`属性来查看`w_data` DataFrame的列名:
```python
print(w_data.columns)
```
确保列名正确拼写和大小写匹配后,再次尝试运行`w_data[w_data['波束场景No'] == cross_data['波束场景No'][0]]`应该就不会报错了。
