CALL test_code(?,?,?,?,?,?)

这是一个 SQL 语句的调用,其中 ? 是占位符,需要根据具体情况填入相应的参数。具体的参数需要根据你的数据库和存储过程的定义来确定。你可以参考下面的示例代码:
```python
import mysql.connector
# 连接数据库
cnx = mysql.connector.connect(user='your_username', password='your_password',
host='your_host', database='your_database')
# 创建游标对象
cursor = cnx.cursor()
# 执行存储过程
args = ('arg1', 'arg2', 'arg3', 'arg4', 'arg5', 'arg6')
cursor.callproc('test_code', args)
# 提交事务
cnx.commit()
# 关闭游标和连接
cursor.close()
cnx.close()
```

[train_x,test_x]=predict(train_x,train_y_scale,test_x,test_y_scale,selected_variables,A_max,fold,method);
As an AI language model, I can infer that the code snippet above is a function call that takes in several arguments. It appears to be calling a function called "predict" and passing in the following arguments:
- train_x: a matrix of training data
- train_y_scale: a vector of scaled training labels
- test_x: a matrix of test data
- test_y_scale: a vector of scaled test labels
- selected_variables: a vector of selected variables to be used in the prediction model
- A_max: a scalar value representing the maximum number of principal components to use in the model
- fold: a scalar value representing the number of folds to use in cross-validation
- method: a string indicating the type of predictive modeling method to use
The function is expected to return two output arguments: train_x and test_x, which are matrices of predicted values for the training and test data, respectively.
Traceback (most recent call last): File "/Users/xiaotang/PycharmProjects/untitled2/SHIYOU.py", line 5, in <module> from networkx.tests.test_all_random_functions import np File "/Users/xiaotang/PycharmProjects/untitled2/venv/lib/python3.8/site-packages/networkx/tests/test_all_random_functions.py", line 1, in <module> import pytest ModuleNotFoundError: No module named 'pytest' Process finished with exit code 1'
这个错误提示是在运行Python代码时出现的,它说找不到名为pytest的模块。这意味着你需要安装pytest模块才能运行这个代码。你可以使用以下命令在终端中安装pytest模块:
```
pip install pytest
```
安装完成后,再次运行代码即可。
