找不到熊猫文件

Question

我不明白为什么Pandas找不到我的fer2013.csv。我有以下代码：

class DataManager(object):
    """Class for loading fer2013 emotion classification dataset or
        imdb gender classification dataset."""
    def __init__(self, dataset_name='imdb', dataset_path=None, image_size=(48, 48)):

        self.dataset_name = dataset_name
        self.dataset_path = dataset_path
        self.image_size = image_size
        if self.dataset_path != None:
            self.dataset_path = dataset_path
        elif self.dataset_name == 'imdb':
            self.dataset_path = '../datasets/imdb_crop/imdb.mat'
        elif self.dataset_name == 'fer2013':
            self.dataset_path = '../datasets/fer2013/fer2013.csv'
        elif self.dataset_name == 'KDEF':
            self.dataset_path = '../datasets/KDEF/'
        else:
            raise Exception('Incorrect dataset name, please input imdb or fer2013')

我收到此错误：

    faces, emotions = data_loader.get_data()

FileNotFoundError: [Errno 2] File ../datasets/fer2013/fer2013.csv does not exist: '../datasets/fer2013/fer2013.csv'

我在那个文件夹中有那个文件，我不知道为什么找不到我的文件。

我解决了这个错误。感谢@DYZ，我可以看到进程正在运行的目录，该进程位于'utils'文件夹中。我将路线更改为“ ./datasets/fer2013/fer2013.csv”，指向“。”。在“ /”之前。
