在ubuntu下使用anaconda安装jittor后运行测试出现此错误：RuntimeError: [f 0514 20:13:59.276076 48 log.cc:608] Check failed ret(256) == 0(0) Run cmd failed: "/home/hongtauo/.cache/jittor/jtcuda/cuda11.2_cudnn8_linux/bin/nvcc"

已解决，安装最新版本的cuda和cudnn即可

您好，我和您的问题相同，请问是需要删除原来的cuda版本，然后再安装新的嘛，还是直接在conda的虚拟环境里更新

下载最新的cuda和cdunn，然后进入conda中jittor的环境里面，将cuda的环境变量添加进去
