cannot import name 'pinv2' from 'scipy.linalg' (D:\APP\Anconda\anaconda3\Lib\site-packages\scipy\linalg\__init__.py)

这个错误通常是由于Scipy版本不兼容或安装不完整导致的。'pinv2'是Scipy中的一个函数，用于计算矩阵的伪逆。出现这个错误可能是因为您的Scipy版本过低或者没有正确安装。

解决这个问题的方法有以下几种：
1. 确保您的Scipy版本是最新的。可以使用以下命令升级Scipy：

   pip install --upgrade scipy

2. 如果升级Scipy后仍然出现问题，可能是因为Scipy没有正确安装。您可以尝试重新安装Scipy：

   pip uninstall scipy
   pip install scipy

3. 如果以上方法都无效，可能是因为您的环境中存在多个Scipy版本冲突。您可以尝试删除所有Scipy相关的包，并重新安装最新版本：

   pip uninstall scipy
   pip uninstall numpy
   pip install numpy
   pip install scipy

希望以上方法能够解决您的问题！

ImportError: cannot import name 'pinv2' from 'scipy.linalg' (C:\Users\86180\AppData\Roaming\Python\Python39\site-packages\scipy\linalg\__init__.py)

这个错误通常出现在您的Scipy版本过低或者安装有问题。您可以尝试更新Scipy版本，方法如下：

pip install --upgrade scipy

如果更新不起作用，您可以尝试重新安装Scipy：

pip uninstall scipy
pip install scipy

如果还是不行，建议检查您的Python环境是否正确配置，或者重新安装Python环境。

cannot import name 'pinv2' from 'scipy.linalg'

The error message you encountered suggests that the 'pinv2' function is not available in the 'scipy.linalg' module. This function is used by the ELMRegressor class in the sklearn_extensions package.

The 'pinv2' function was introduced in SciPy version 1.7.0. If you are using an older version of SciPy, you may encounter this error. To resolve this issue, you can upgrade your SciPy package to the latest version by running the following command:

pip install --upgrade scipy

After upgrading SciPy, try importing ELMRegressor again. It should now be able to find the 'pinv2' function without any issues.

If you already have the latest version of SciPy installed and still encounter this error, it could be due to a compatibility issue between the sklearn_extensions and SciPy versions. In such cases, you may need to use an older version of sklearn_extensions or find an alternative implementation for ELM regression that is compatible with your setup.
