我已经从 yann.lecun.com 下载了 MNIST 训练图像和标签并将它们解压缩。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,我收到此错误-
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。我怎样才能解决这个问题?
编辑:我尝试了同样的python-mnist
包装-
from mnist import MNIST
mndata = MNIST('/python/mnist-files')
features,labels = mndata.load_training()
我遇到了类似的错误-
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'
该错误似乎仅与培训标签文件有关;我尝试重新下载文件,但没有解决它。
编辑 2:根据要求,这是ls -l /python/mnist-files

编辑3:这是输出print(os.listdir('/python/mnist-files'))
:
FileNotFoundError: [Errno 2] No such file or directory: '/python/mnist-files'
我完全被迷惑了——我知道该目录存在!当我 cd into 时我可以看到它/python
!
