cannot import name 'cross_validation' from 'sklearn' (C:\Users\lab408\anaconda3\lib\site-packages\sklearn\__init__.py)

这个错误通常是由于sklearn版本更新导致的。在新版本中,cross_validation已被弃用,应该使用model_selection代替。你可以尝试以下代码来解决这个问题:
```python
from sklearn.model_selection import train_test_split
```
这将从model_selection模块中导入train_test_split函数,该函数可以用于将数据集划分为训练集和测试集。如果你需要使用cross_validation的其他函数,也可以从model_selection中导入它们。

cannot import name 'cross_validation' from 'sklearn' (C:\Users\86183\miniconda3\lib\site-packages\sklearn\__init__.py)
这个错误是由于无法从'sklearn'中导入'cross_validation'引起的。在最新版本的sklearn库中,'cross_validation'已经被重命名为'model_selection'。因此,您需要在代码中将'cross_validation'替换为'model_selection'来解决这个问题。根据您提供的错误信息,可以看到在引用中出现的文件路径是"C:\Users\joesh\Desktop\Python\Machine Learning\1st tutorial.py"和"C:\Users\joesh\Desktop\Python\lib\site-packages\sklearn\__init__.py"。而在引用和引用中出现的文件路径分别为"C:\Users\myname\Anaconda3\lib\site-packages\sklearn\model_selection\_validation.py"。因此,您需要在这两个文件中进行相应的修改。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

cannot import name 'cross_validation' from 'sklearn'
The error message suggests that there is an issue with importing the `cross_validation` module from the `sklearn` package.
Starting from `sklearn` version 0.22, the `cross_validation` module has been moved to `model_selection`. Therefore, you might want to check if you are using an outdated version of `sklearn`.
To fix this error, you can replace `cross_validation` with `model_selection` in your import statement. For example, instead of:
```
from sklearn.cross_validation import train_test_split
```
You can use:
```
from sklearn.model_selection import train_test_split
```
If you are using an older version of `sklearn` and cannot update it, you can try installing an older version of the package that still has the `cross_validation` module. You can check the release notes of each `sklearn` version to see if it has the `cross_validation` module or not.
