这个错误通常是由于尝试使用列表索引时传入了一个元组而不是整数或切片引起的。在你的代码中,出现了这个错误的地方是在 `plot_sensor_nodes` 函数中的 `unknown_node_positions[:, 0]`。
要解决这个问题,你需要确保 `unknown_node_positions` 是一个可索引的列表或数组。你可以尝试将其转换为一个 NumPy 数组,如下所示:
```python
import numpy as np
unknown_node_positions = np.array(unknown_node_positions)
```
然后,你就可以像使用传统的二维数组一样进行索引操作:
```python
unknown_x = unknown_node_positions[:, 0]
```
这样应该能够解决你遇到的问题。如果还有其他问题,请随时提问。
