CAN矩阵-TypeError：None类型对象不可迭代

Question

当文件转换为在Anaconda导航器中执行的exe时，获取TypeError。不确定软件包的依赖性或exe转换问题。

代码错误1

Exception in Tkinter callback
Traceback (most recent call last):
  File "tkinter\__init__.py", line 1699, in __call__
  File "Smart_Fn.py", line 244, in openFile
    convert(infile, outfile)
  File "Smart_Fn.py", line 80, in convert
    for name in dbs:
TypeError: 'NoneType' object is not iterable

        dbs = canmatrix.formats.loadp(infile, **options)
