我是tensorflow的新手,所以我试图首先测试我的基本功能。我有用于读取数据以下Python方法:如何验证张量包含图像数据tensorflow
def read_data(filename_queue):
# Whole file reader required for jpeg decoding
image_reader = tf.WholeFileReader()
# We don't care about the filename, so we ignore the first tuple
_, image_file = image_reader.read(filename_queue)
# Decode the jpeg images and set them to a universal size
# so we don't run into "out of bounds" issues down the road
image_orig = tf.image.decode_jpeg(image_file, channels=3)
image = tf.image.resize_images(image_orig, [224, 224])
return image
“filename_queue”是路径个别JPEG文件中的“图像”子目录的队列。我运行一个for循环遍历文件名,以确保唯一与有效路径被添加到队列:
filenames = []
for i in range(1000):
filename = os.path.join(os.path.dirname(os.path.realpath(__file__)),
"./images/seatbelt%d.jpg" % i)
if not tf.gfile.Exists(filename):
# print("Filename %s does not exist" % filename)
continue
else:
filenames.append(filename)
# Create a string queue out of all filenames found in local 'images' directory
filename_queue = tf.train.string_input_producer(filenames)
input = read_data(filename_queue)
我想断言,图像被读取正确的,所有的数据都是包含在重构的张量中。我怎么能这样做?
