我正在尝试使用MNISTSuperpixels数据进行图卷积，但是在使用示例代码时遇到了一些麻烦.大多数脚本都在使用 path = osp.join(osp.dirname(osp.realpath(__ file__))，'..'，'data'，'MNIST')但是，他们给了我一个错误 NameError:名称'__file__'未定义，我不理解 osp.realpath(__ file __)的真正含义.
I'm trying to use MNISTSuperpixels data for graph convolution, but I have some troubles using the example code.Most of scripts were usingpath = osp.join(osp.dirname(osp.realpath(__file__)), '..', 'data', 'MNIST')However, they gave me an errorNameError: name '__file__' is not defined and I don't understand what osp.realpath(__file__) really means.
我在Ubuntu上使用Jupyter笔记本，我的工作目录为
I'm using Jupyter notebook on Ubuntu, and my working directory is
print(os.getcwd())
/home/hkimlx/GDL/pytorch_geometric/examples
与示例代码 mnist_nn_conv.py 所在的目录相同.
which is the same directory where the sample code mnist_nn_conv.py is located.
请帮助我.谢谢！
推荐答案
在笔记本中，您需要使用双引号"__file__"就像 osp.realpath("__ file __")一样，而不是 osp.realpath(__ file __)
In notebook, you need to use double quoted "__file__" as in osp.realpath("__file__") instead of osp.realpath(__file__)
