再トレーニングするとき、トレーニングデータ用の形状 [299,299] の画像 (すべて jpeg エンコード) でファイルをinception_v3 network作成します。TFrecorde結果だけを取得するstep=0と、次のようなエラーが発生します。
tensorflow.python.framework.errors_impl.InvalidArgumentError: reshape への入力は 89401 の値を持つテンソルですが、要求された形状は 268203 です
[[ノード: Reshape = Reshape[T=DT_UINT8, Tshape=DT_INT32, _device="/job:localhost/replica:0/task:0/device:CPU:0"](DecodeRaw, Reshape/shape)]]
89401=299×299、268023=299×299×3。私の作成TFrecordeコードは次のとおりです。

for img_name in os.listdir(class_path):

img = Image.open(img_path)

batch_size=32, num_threads=4, capacity=300)
label_batch = tf.one_hot(label_batch, depth=6)
label_batch = tf.cast(label_batch, dtype=tf.int32)
label_batch = tf.reshape(label_batch, [32, 6])
with tf.Session() as sess:
coord = tf.train.Coordinator()
threads = tf.train.start_queue_runners(coord=coord)
try:
imgs, labs = sess.run([image_batch, label_batch])
imgs = tf.to_float(imgs)
init_op = tf.global_variables_initializer()
sess.run(init_op)
except tf.errors.OutOfRangeError:
print('Done training -- epoch limit reached')
coord.request_stop()
coord.join(threads)
array = imgs.eval()
print("##########################################")
for i in range(32):
ar = array[i].flatten()
print(len(ar))
print('#######################################')
sess.close()
return imgs, labs
その上、私のクラスはクラスごとに6、32枚の画像です。batch_size = 32. トレーニング前に画像マトリックスのサイズを「2680203」と出力します。出力ログは次のとおりです。

なぜ私はstep=0結果しか得られないのですか。次に、エラーが発生します。スタック トレースは次のとおりです。
