Traceback (most recent call last): File "D:\文档\pythonProject\main.py", line 56, in <module> merge_1=pd.merge(df1,df2,df3,df5,on=['year','month','Stkcd']) TypeError: merge() got multiple values for argument 'on'

这是因为`pd.merge()`函数的参数中有多个DataFrame同时使用了`on`参数,导致了该错误。正确的写法是将所有的DataFrame作为一个列表传入`pd.merge()`函数,并使用`on`参数指定合并所需的列名,例如:
```
merge_1 = pd.merge([df1, df2, df3, df5], on=['year', 'month', 'Stkcd'])
```
这样就可以将所有的DataFrame按照指定的列名进行合并了。

这个错误提示是 Python 中的 YAML 库的问题,可能是因为该库的版本过低或者使用方式不正确导致的。你可以尝试升级 PyYAML 库的版本,或者使用 `yaml.safe_load()` 方法代替 `yaml.load()` 方法。例如:
```python
import yaml
with open("config.yaml", "r") as f:
data = yaml.safe_load(f)
```
另外,你也可以检查一下 `deep_sort.yaml` 配置文件存在,以及该文件是否符合 YAML 的语法规范。

这个错误是由于在使用Matplotlib绘制图形时,没有正确地设置图像的显示格式所导致的。可以将Matplotlib的显示格式设置为Tkinter的Agg格式,尝试使用以下代码来解决这个问题:
```python
import matplotlib
matplotlib.use('TkAgg')
import matplotlib.pyplot as plt
```
这样可以将Matplotlib的显示格式设置为Tkinter的Agg格式,从而避免这个错误。如果还是出现问题,可以尝试更新Matplotlib或者重新安装Matplotlib来解决。同时,还要注意确认图像是否存在,确保图像的路径和文件名是否正确。
