R语言深度学习，报错

对数据集中的标签数据进行处理，报错参数长度错误 ，还有警告

keras包中的to_categorical函数

> train_lab1 <- factor(train_data$label,levels = labelname,labels = 0:9)
> val_lab1 <- factor(val_data$label,levels = labelname,labels = 0:9)
> test_lab1 <- factor(test_data$label,levels = labelname,labels = 0:9)
> train_lab <- to_categorical(train_lab1,num_classes = 10)

Error in Sys.setenv(PATH = new_path) : wrong length for argument

In addition: Warning messages:

后面代码也是报错

```r
> val_lab <- to_categorical(val_lab1,num_classes = 10)

感觉是用到keras包的函数就会报错，第一次用R跑深度学习，在网上看了要配置一些东西，是不是配置那方面搞错了
