我想用我的训练模型测试一些示例，但是在测试过程中会发生错误，请告诉我我的代码中的错误集中在第94行：
line90：var_output_2 = tf.Variable(0, dtype=tf.float32,name="a",trainable=False,validate_shape=False)
line91: row_vector = tf.gather_nd(word_embeddings, self.word_error_embed, name="a_word_error_embed")
line92: sum_all = tf.reduce_sum(row_vector, 1, name="a_reduce_sum")
line93: var_output_3=tf.assign(var_output_2, word_embeddings, validate_shape=False)
line94: word_embeddings = tf.scatter_nd_update(var_output_3, self.error_word, sum_all)
控制台错误如下：
tensorflow.python.framework.errors_impl.InvalidArgumentError: Must have updates.shape = indices.shape[:batch_dim] + params_shape[slice_dim:], got updates.shape: [7,300], indices.shape: [7,1], params_shape: [7,9,300], slice_dim: 1, and batch_dim: 1
