Odoo 14/Python：FileNotFoundError：[Errno 2] 没有这样的文件或目录：'/events/img\\models'

如何解决Odoo 14/Python：FileNotFoundError：[Errno 2] 没有这样的文件或目录：'/events/img\\models'

我是 python 新手，不知道如何解决这个错误。请指导我。我的目标是将我在图像字段中上传的图像保存在名为“img”的子文件夹中，该子文件夹位于我的“事件”模块下。

我收到以下错误：

[
    {
        "name": "apple","values": [2,3,4]
    },{
        "name": "orange","values": [1,2,{
        "name": "pear",]

完整代码如下：

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\virtual_odoo14\Scripts\odoo\http.py",line 639,in _handle_exception
    return super(JsonRequest,self)._handle_exception(exception)

    raise exception.with_traceback(None) from new_cause

这是我要实现的目标的具体代码：
