Python 回溯（最近一次调用）：NameError:name'；路径'；没有定义

我对Python这个主题还不熟悉。我在进行自动驾驶时传输了数据，最后得到了如下错误：

Traceback (most recent call last):
  File "c:\Users\eminn\Desktop\Autopilot_V2\LoadData_V2.py", line 46, in <module>
    return_data()
  File "c:\Users\eminn\Desktop\Autopilot_V2\LoadData_V2.py", line 29, in return_data
    full_path = os.path.join(DATA_FOLDER, path)
NameError: name 'path' is not defined

之前，它给出了一个来自tensorflow模块的错误。在我下载tensorflow之后，我又一次这么做了，但我在几内亚遇到了一个错误。

从现在开始谢谢您。

您已经注释掉了

路径

变量，您需要定义它或取消注释它
