Errno 13在传输v3时

Question

所以我几周前刚学了python，我对tensorflow还不熟悉。但我需要对inception模型进行微调。当我试着学习一些教程时，当我终于开始看到一些光明时，我犯了一个可怕的错误，我无法摆脱。以下是代码中出现错误的部分：

import matplotlib.pyplot as plt

train_dir=r'C:\tf_files'

image_paths=train_dir

images = [plt.imread(train_dir) for path in image_paths]

def plot_images(images, cls_true, cls_pred=None, smooth=True):
    assert len(images) == len(cls_true)

    # Create figure with sub-plots.
    fig, axes = plt.subplots(3, 3)

    # Adjust vertical spacing.
    if cls_pred is None:
        hspace = 0.3
    else:
        hspace = 0.6
    fig.subplots_adjust(hspace=hspace, wspace=0.3)

    # Interpolation type.
    if smooth:
        interpolation = 'spline16'
    else:
        interpolation = 'nearest'

    for i, ax in enumerate(axes.flat):
        # There may be less than 9 images, ensure it doesn't crash.
        if i < len(images):
            # Plot image.
            ax.imshow(images[i],
                      interpolation=interpolation)

            # Name of the true class.
            cls_true_name = class_names[cls_true[i]]

            # Show true and predicted classes.
            if cls_pred is None:
                xlabel = "True: {0}".format(cls_true_name)
            else:
                # Name of the predicted class.
                cls_pred_name = class_names[cls_pred[i]]

                xlabel = "True: {0}\nPred: {1}".format(cls_true_name, cls_pred_name)

            # Show the classes as the label on the x-axis.
            ax.set_xlabel(xlabel)

        # Remove ticks from the plot.
        ax.set_xticks([])
        ax.set_yticks([])

    # Ensure the plot is shown correctly with multiple plots
    # in a single Notebook cell.
    plt.show()

这就是终点站吐出的东西：

我基本上需要一种方法把一个图像做成一个数组，但我想不出来。 任何帮助都将不胜感激，非常感谢。和平！你知道吗

Answer 1

编辑：您调用了imread来获取一个目录，它实际上不是一个图像。你的图像在C:\tf_files吗？如果是这样，请使用os.listdir()获取目录中的所有（包括非映像）文件。所以你的代码应该是这样的：

train_dir=r'C:\tf_files' # The directory contains images    
image_paths=os.listdir(train_dir)  # Get the image file only, you can check by checking its extension   
images = [plt.imread(train_dir) for path in image_paths]  

还有一件事：引发了Permission denied错误，这让我感到困惑。如果我的回答能帮助您解决问题，这意味着错误不是由于所有权引起的，所以我不知道为什么会发生这种情况。你知道吗

这就是问题所在PermissionError: [Errno 13] Permission denied: 'C:\\tf_files'
您有权访问C:\\tf_files目录吗？试着获得所有权，或者只是编辑你可以访问的某个地方的路径
