Question

我正在构建手写文本识别nn，并且我尝试执行此代码，但是我得到了“ zip参数＃2必须支持迭代”，并且我不明白为什么会发生此错误请帮助

char_arr = [c for c in r"""i(jQXr).gA&t#enw75:0l6*2KVOz/hL-?UIP'bv,McTJ9pdY4xfy3+"N1ZHDSqGWCFE!skRoB;8uam"""]
num_dic = {n: i for i, n in enumerate(char_arr)}

global_step = tf.Variable(0,trainable=False)

Y = tf.sparse_placeholder(tf.int32)

data_label = 'apple'

indices = [[i] for i in range(0,len(data_label))]
values = [char_arr.index(c) for c in list(data_label)]
shape = [len(data_label)]
label = tf.SparseTensorValue(indices, values, shape)

label = tf.convert_to_tensor_or_sparse_tensor(label)


sess.run(optimizer, feed_dict={X : model, Y : label, keep_prob : 0.6})

print('Step :',global_step,', label :',data_label)

我得到了这些错误：

TypeError: zip argument #2 must support iteration

为什么“ zip参数必须支持迭代”，此代码中出现错误？
