我对R代码有疑问： -我有此代码行
mx.exec.update.arg.arrays(exec_D, arg.arrays = list(data=D_values_fake,label=mx.nd.array(rep(0, batch_size))), match.name=TRUE)
exec_D包含：
C++ object <00000000145f0e50> of class 'MXExecutor' <00000000138b30a0>
arg.arrays包含：
$ {
data$data$softmaxoutput0_output[，1] [，2] [，3] [，4] [，5] [，6] [，7] [，8] [，9] [，10] [，11] [，12] [， 13] [，14] [，15] [，16] [，17] [，18] [，19] [，20] [，21] [，22] [，23] [，24] [，25] [，26] [，27] [，28] [，29] [，30] [1，] 1 1 1 1

但是运行此行时出现此错误：
exec $ update.arg.arrays（arg.arrays，match.name，skip.null）中的错误：
需要一个外部指针：[type = list]。
