你可以将传递给`mtf.transform()`函数的数组转换为2D数组。你可以使用`numpy.reshape()`函数将1D数组转换为2D数组,如下所示:
```python
import numpy as np
# 将1D数组转换为2D数组
normalized_beat_2d = np.reshape(normalized_beat, (-1, 1))
# 对2D数组进行转换
image[i] = mtf.transform(normalized_beat_2d)
```
这样应该就能解决你遇到的问题了。

这个错误提示说明在GetBeats.py文件的第32行,你正在尝试将一个列表(list)转换成一个浮点数类型(float)。但是,列表(list)类型没有astype()方法,所以会出现 'list' object has no attribute 'astype' 的错误。
为了解决这个问题,你需要将列表(list)转换成NumPy数组(numpy array),因为NumPy数组(numpy array)有astype()方法可以将其转换成浮点数类型。
你可以使用以下代码将列表(list)转换成NumPy数组(numpy array):
```
import numpy as np
beat = np.array(beat).astype(float)
```
这应该可以解决你的问题。

这个错误提示是因为你使用了一个名为HeartPy的模块,但在该模块中没有名为"peak_detection"的属性或函数。你可以检查一下HeartPy模块中是否有其他的函数或属性可以替代"peak_detection"函数。另外,你也可以尝试在HeartPy模块的官方文档中查找相关信息,或者联系该模块的开发者以获取帮助。
