Question

因此，当我尝试运行我的代码时，它一直说它无法找到图像，但它实际上就在那里。我尝试了很多东西，但没有任何作用。有人可以帮帮我吗？这是代码试图从nist数据集读取图像，然后我试图训练模型。这是我的代码和错误代码：

import os
import cv2
import tensorflow as tf

upper_level_dirs = open("/Users/cam/reader/top_level_dirs")
upper_level_dirs = upper_level_dirs.read().split()

print(upper_level_dirs)

file_names = []
labels = []

for folder in upper_level_dirs:
    for filename in os.listdir("./train/" + folder + "/"):
        file_names.append("./train/" + folder + "/" + filename)
        labels.append(folder)


# Use a custom OpenCV function to read the image, instead of the standard
# TensorFlow `tf.read_file()` operation.
def _read_py_function(file_name, label):
  image_string = tf.read_file(filename)
  image_decoded = tf.image.decode_image(image_string, channels=3)
  image_resized = tf.image.resize_image_with_crop_or_pad(image_decoded, 28, 28)
  return image_resized, label
  # image_decoded = cv2.imread(file_name.decode(), cv2.IMREAD_GRAYSCALE)
  # return image_decoded, label




dataset = tf.data.Dataset.from_tensor_slices((file_names, labels))

dataset = dataset.map(_read_py_function)

sess = tf.InteractiveSession()

dataset = dataset.batch(32)
iterator = dataset.make_initializable_iterator()
next_element = iterator.get_next()

for _ in range(100):
  sess.run(iterator.initializer)
  while True:
    try:
      sess.run(next_element)
    except tf.errors.OutOfRangeError:
      break

Answer 1

我也发现该错误，我的解决方法是：也许您是通过Windows创建路径，并且当使用notepad ++查看txt时，路径以'CR'结尾，而linux无法读取。您可以用记事本++将“ CR”替换为“”。然后就可以了。

Tensorflow无法找到文件
