加载MNIST数据集时如何解决'No such file or directory'错误”

Question

我已经从yann.lecun.com下载了MNIST训练图像和标签，并解压缩了它们。我正在尝试使用此代码加载它们-

from mlxtend.data import loadlocal_mnist

features,labels = loadlocal_mnist(
    images_path='/python/mnist-files/train-images-idx3-ubyte',
    labels_path='/python/mnist-files/train-labels-idx1-ubyte')

但是，出现此错误-

Traceback (most recent call last):
  File "generateClassifier.py", line 12, in <module>
    labels_path='/python/mnist-files/train-labels-idx1-ubyte')
  File "/home/inglorion/.local/lib/python3.6/site- 
packages/mlxtend/data/local_mnist.py", line 36, in loadlocal_mnist
    with open(labels_path, 'rb') as lbpath:
FileNotFoundError: [Errno 2] No such file or directory: '/python/mnist- 
files/train-labels-idx1-ubyte'

该目录确实存在，并且文件名正确。我该如何解决？

编辑：我对python-mnist包尝试了相同的操作-

from mnist import MNIST
mndata = MNIST('/python/mnist-files')
features,labels = mndata.load_training()

我遇到类似的错误-

Traceback (most recent call last):
  File "generateClassifier.py", line 11, in <module>
    features,labels = mndata.load_training()
  File "/home/inglorion/.local/lib/python3.6/site-packages/mnist/loader.py", 
line 126, in load_training
    os.path.join(self.path, self.train_lbl_fname))
  File "/home/inglorion/.local/lib/python3.6/site-packages/mnist/loader.py", 
line 247, in load
    with self.opener(path_lbl, 'rb') as file:
  File "/home/inglorion/.local/lib/python3.6/site-packages/mnist/loader.py", 
line 239, in opener
    return open(path_fn, *args, **kwargs)
FileNotFoundError: [Errno 2] No such file or directory: '/python/mnist- 
files/train-labels-idx1-ubyte'

该错误似乎仅与训练标签文件有关；我尝试重新下载文件，但是并没有解决。

编辑2：根据要求，这是ls -l /python/mnist-files-]的输出>

编辑3：这是print(os.listdir('/python/mnist-files'))的输出：

FileNotFoundError: [Errno 2] No such file or directory: '/python/mnist-files'
我完全迷惑了-我知道

目录存在！当我进入/python时可以看到它！

Answer 1

os.dir('/')

Answer 2

from tensorflow.examples.tutorials.mnist import input_data
mnist = input_data.read_data_sets('MNIST_data', validation_size=0)

我已经执行了代码，它工作正常！！希望对您有所帮助。
