请问，这个是什么原因造成的？是因为对测试的图片有什么要求吗？我如果不修改图像的大小会出现cannot reshape array of size 3200 into shape(1,32,32)的问题，调整大小后会出现上面这个问题。因为我是刚接触，遇到了很多问题，这个问题我实在不知道怎么解决，希望您能提供一下方法，谢谢了。
你好，我在训练完成后在网上找了一张图进行测试，但是出现了如下的问题： `tensorflow.python.framework.errors_impl.FailedPreconditionError: sequence_length(0) <= 21 [[Node: CTCBeamSearchDecoder = CTCBeamSearchDecoder[beam_width=100, merge_repeated=true, top_paths=1, _device="/job:localhost/replica:0/task:0/device:CPU:0"](logits/transpose/_105, _arg_time_step_len_0_2)]] [[Node: SparseToDense/_107 = _Recv[client_terminated=false, recv_device="/job:localhost/replica:0/task:0/device:GPU:0", send_device="/job:localhost/replica:0/task:0/device:CPU:0", send_device_incarnation=1, tensor_name="edge_399_SparseToDense", tensor_type=DT_INT64, _device="/job:localhost/replica:0/task:0/device:GPU:0"]()]]
