R code: tryCatch

test <- tryCatch({
          lrelu(layer_output)
          TRUE
        }, error=function(e){
          print(paste("error in lrelu:infinite weights/bias,try end early"))
          FALSE
        })
        if (test) {#print(c(i,layer_input,weights,biases,layer_output,layer_inputs,layer_outputs))

怀疑是lrelu(layer_output)出了问题，所以在函数代码里加上tryCatch(),可以在报错的同时print一些需要的信息
