处理 Runtime Error: one of the variables needed for gradient computation has been

两次遇到这个问题，记录一下

1、反向传播时报错，参考 在用pytorch跑生成对抗网络的时候，出现错误Runtime Error: one of the variables needed for gradient computation has been_qq_33093927的博客-CSDN博客最近在看GAN，遇到了些问题，发现是前人踩过的坑，确实帮到了我，集中整理下吧目录问题环境配置解决过程总结问题在用pytorch跑生成对抗网络的时候，出现错误Runtime Error: one of the variables needed for gradient computation has been modified by an inplace operation，特记录排坑记录。环境配置windows10 2004python 3.7.4pytorch 1https://blog.csdn.net/qq_33093927/article/details/124063916?spm=1001.2101.3001.6650.5&utm_medium=distribute.pc_relevant.none-task-blog-2%7Edefault%7EBlogCommendFromBaidu%7ERate-5-124063916-blog-125728708.pc_relevant_recovery_v2&depth_1-utm_source=distribute.pc_relevant.none-task-blog-2%7Edefault%7EBlogCommendFromBaidu%7ERate-5-124063916-blog-125728708.pc_relevant_recovery_v2&utm_relevant_index=6核心就是把optimizer.step()挪到梯度计算的后面

2、反向传播前的计算报错，参考里面第三点
