当我更改新图像以训练im2txt模型时出错。不知道为什么。
Build the model.
bazel build -c opt im2txt/...
bazel-bin/im2txt/train
--input_file_pattern="${MY_DATA_DIR}/train-?????-of-00256"
--inception_checkpoint_file="${INCEPTION_CHECKPOINT}"
--train_dir="${MODEL_DIR}/train"
--train_inception=false
--number_of_steps=10000
在句子
下运行时出错sequence_length = tf.reduce_sum(self.input_mask, 1)
lstm_outputs, _ = tf.nn.dynamic_rnn(cell=lstm_cell,
inputs=self.seq_embeddings,
sequence_length=sequence_length,
initial_state=initial_state,
dtype=tf.float32,
scope=lstm_scope)
