ValueError: The `Wavelet` class is for discrete wavelets, cgau1 is a continuous wavelet. Use pywt.ContinuousWavelet instead

这个错误是由于您正在尝试使用PyWavelets中的离散小波变换,但是您提供的小波名称“cgau1”是连续小波,因此应该使用`pywt.ContinuousWavelet`类而不是`pywt.Wavelet`类。请尝试更改您的代码以使用`pywt.ContinuousWavelet('cgau1')`而不是`pywt.Wavelet('cgau1')`。

ValueError: the greenlet library is required to use this function.
This error occurs when a function in a Python program requires the greenlet library to be installed, but it is not found on the system.
To resolve this error, you can install the greenlet library using pip, a package manager for Python. Open a terminal or command prompt and type the following command:
```
pip install greenlet
```
This will download and install the greenlet library on your system. Once it is installed, you should be able to use the function that requires it without encountering the ValueError.
ValueError: The name 'index1' is already registered for this blueprint. Use 'name=' to provide a unique name.
这是一个 Python 报错信息,它表明在一个 Blueprint 蓝图中出现了重复的名称('index1')。解决这个问题的方法是为这个 Blueprint 指定一个唯一的名称,可以通过在注册 Blueprint 时通过 'name' 参数来设置。例如:
```python
from flask import Blueprint
bp = Blueprint('my_blueprint', __name__)
@bp.route('/')
def index():
return 'Hello, world!'
```
