具体报错信息如下，有没有哪位大佬遇到过

遇到了同样的问题，请问解决没
我改用了paddle2.4.2，重新安装了cuda11.2和cudnn8.2.1这两个版本，再用conda安装paddle之后没遇到这个报错了
我用paddlepaddle-gpu 0.0.0.post112版本出现了上面的错误OSError: (External) CUBLAS error(15)。但如果在.ipynb文件下，先在一个单元格下运行import paddle
paddle.utils.run_check()进行gpu检测，在检测到gpu后，再运行后面带gpu的代码时，OSError: (External) CUBLAS error(15)的错误就不会发生了。
import paddle
paddle.utils.run_check()
有用！！！！！
