module 'numpy' has no attribute '__version__'

报错"module 'numpy' has no attribute '__version__'"是因为在你的代码中使用了numpy的版本属性__version__，但是该属性在较旧的numpy版本中可能不存在。根据引用提供的解决方案，有两个可能的解决方法:

1. 第一个解决方法是重新安装numpy的特定版本。你可以使用命令"pip uninstall numpy"卸载当前版本的numpy，然后使用命令"pip install numpy==1.22"安装指定的版本1.22。这样可以确保你的numpy版本与代码兼容。

2. 第二个解决方法是更新你的代码，以适应较新的numpy版本。你可以修改代码中使用numpy版本属性__version__的部分，或者使用其他方法来获取numpy的版本信息。这样可以使你的代码在较新的numpy版本中正常工作。

module numpy has no attribute

This error message usually occurs when you try to access an attribute or method that doesn't exist in the NumPy module. Here are some possible solutions:

1. Check the spelling of the attribute or method you are trying to access. Make sure it is spelled correctly and that it is a valid attribute or method in NumPy.

2. Make sure you have imported the NumPy module correctly. You can import NumPy using the following code:

import numpy as np

This will allow you to use NumPy functions and attributes using the "np" alias.

3. If you are using an older version of NumPy, some attributes or methods may not exist. Try updating NumPy to the latest version.

4. If none of the above solutions work, try restarting your Python environment (e.g. Jupyter notebook, Python IDE) and re-importing NumPy. Sometimes, this can solve the issue.

module numpy has no attribute matnul

I believe you meant to write "matmul" instead of "matnul". "matmul" stands for matrix multiplication in NumPy. If you are facing an error "module numpy has no attribute matmul", it could be because you might have a typo in your code or you might be using an older version of NumPy that does not support the "matmul" function.

To fix this, try updating your NumPy version to the latest one using the following command:

pip install --upgrade numpy

If you still face the issue, make sure that you have imported NumPy correctly in your code using the following statement:

import numpy as np

Then, you can use the "matmul" function as follows:

result = np.matmul(matrix1, matrix2)

Here, "matrix1" and "matrix2" are two matrices that you want to multiply.
