Using MNIST to load a dataset but getting file not found error, Windows 10, Python 3
If you are encountering a "file not found" error while trying to load the MNIST dataset in Python on Windows 10, it may be due to a file path issue or missing dataset files. To resolve this, you can try the following steps:
Ensure the
idx
files are present: The MNIST dataset consists of fouridx
files:train-images-idx3-ubyte
,train-labels-idx1-ubyte
,t10k-images-idx3-ubyte
, andt10k-labels-idx1-ubyte
. Make sure that these files are available in the expected location. You can download the dataset from the official MNIST website (http://yann.lecun.com/exdb/mnist/) if needed.Verify the file path: Double-check that the file path you are using to load the dataset is correct. Ensure that it includes the correct directory path and file extensions. If the dataset files are in a different directory, make sure to provide the correct path when loading the dataset.
Use absolute file paths: Instead of relying on relative file paths, consider using absolute file paths to ensure the exact location of the dataset files is specified. You can use the
os.path
module to construct the absolute path dynamically. Here's an example:pythonimport os
# Specify the directory where the dataset files are located
dataset_dir = r'C:\path\to\mnist\dataset'
# Construct the absolute file paths
train_images_file = os.path.join(dataset_dir, 'train-images-idx3-ubyte')
train_labels_file = os.path.join(dataset_dir, 'train-labels-idx1-ubyte')
test_images_file = os.path.join(dataset_dir, 't10k-images-idx3-ubyte')
test_labels_file = os.path.join(dataset_dir, 't10k-labels-idx1-ubyte')
# Use the absolute file paths to load the dataset
# Your code here
Replace
C:\path\to\mnist\dataset
with the actual directory path where your MNIST dataset files are located.Verify file permissions: Ensure that the dataset files have appropriate read permissions. Right-click on each file, go to "Properties," and make sure that the files are not set as "Read-only" and that your user account has read access.
By following these steps, you should be able to address the "file not found" error and successfully load the MNIST dataset in Python on Windows 10.
