Traceback (most recent call last): File "D:\jiqixuexi\main.py", line 16, in <module> X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=202121121078)是什么意思,该怎么改

这段代码是使用 scikit-learn 库中的 train_test_split 函数将数据集 X 和标签 y 拆分为训练集和测试集,其中 test_size=0.3 表示将数据集中的 30% 分配给测试集,random_state=202121121078 用于设置随机数生成器的种子,以确保每次运行代码时都会得到相同的结果。
如果你想更改拆分比例,可以修改 test_size 参数的值。如果你想使用不同的随机种子,也可以将 random_state 参数的值改变。例如,你可以将拆分比例修改为 0.2,随机种子修改为 42,代码如下:
```python
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
```

这是一个 Python 的错误,看起来是在使用 PaddlePaddle 框架时出现了问题。可能是因为缺少某个依赖项或环境配置不正确导致的。你可以尝试更新 PaddlePaddle 和相关的依赖项,或者检查你的环境配置是否正确。如果问题仍然存在,请查看错误信息中的文件和行号,以便更好地定位和解决问题。
Traceback (most recent call last): File "D:\jiqixuexi\main.py", line 62, in <module> roc_auc = auc(fpr, tpr) TypeError: 'numpy.float64' object is not callable是什么意思,该怎么改
这个错误通常是因为在代码中将一个变量命名为了函数名,导致函数被覆盖,从而出现这个错误。在这个错误信息中,错误的来源是`auc`这个函数被当做了一个`numpy.float64`类型的变量来使用,而不是当做函数来使用。
为了解决这个问题,需要检查代码中是否有将函数名覆盖的情况,或者检查变量是否被错误地赋值为函数名。可以尝试重新命名变量名,或者使用`del`语句删除变量,以确保函数名没有被覆盖。
例如,可以尝试使用以下命令删除变量并重新计算AUC:
```python
# 删除可能存在的变量
del auc
# 重新计算AUC
roc_auc = sklearn.metrics.auc(fpr, tpr)
```
这里我们使用`del auc`删除了名为`auc`的变量,然后使用`sklearn.metrics.auc`重新计算AUC。注意要导入`sklearn.metrics`模块,然后使用`sklearn.metrics.auc`函数来计算AUC。
