[英]How to delete CMD instructions so I can run program in IDE console (Python)?
我有一个代码(如下),仅当它从CMD执行时才运行。 我需要对其进行修改,并且它必须在IDE控制台(Eclipse)中运行。
当我尝试在Eclipse中执行此操作时,出现以下错误:
Traceback (most recent call last):
File "C:\Users\User\workspace\TF\TF\predict_2.py", line 138, in <module>
main(sys.argv[1])
IndexError: list index out of range
需要做什么?
我正在阅读有关__main__
和sys.argv
但我不太了解...

就像@JCooke所说的那样,必须通过删除/插入“其他”在main(sys.argv[1])
修改代码。
就我而言,我必须在IDE控制台中查看图像的处理。 在CMD中,我必须提出一个论点,该论点必须是图像本身的路径。 在代码中,我使用图像的路径更改了sys.argv[1]
