非常抱歉,我之前给出的修改仍然存在问题。根据您提供的错误信息,`cupyx.scipy.signal`模块中没有名为`lfilter`的属性。在GPU上应用滤波器时,CuPy库中没有直接的替代函数。
为了在GPU上应用滤波器,您可以使用`cupyx.scipy.signal.filtfilt`函数来执行零相移滤波。`filtfilt`函数可以应用一个滤波器的前向和反向传递,从而实现零相移滤波。
请尝试使用以下修改后的代码:
```python
import numpy as np
import cupy as cp
from scipy import signal
class Channelizer(object):
"""
Channelizer object.
\param filter_coeffs: Filter coefficient array.
"""
_channel_num: int
_filter_coeffs: np.ndarray
def __init__(
self,
filter_coeffs: np.ndarray,
channel_num: int = 8):
assert isinstance(channel_num, int)
self._filter_coeffs = np.reshape(filter_coeffs, (channel_num, -1), order='F')
self._channel_num = channel_num
