bug描述 Describe the Bug

Ubuntu 20.04 安装 PaddlePaddle 使用命令： conda install paddlepaddle-gpu==2.4.0 cudatoolkit=11.6 -c Paddle -c conda-forge 新建的 Conda 环境，安装脚本执行成功，但 import paddle 时报错：

>>> import paddle
Error: Can not import paddle core while this file exists: /cpfs/user/zhaochenxu1/software/anaconda3/envs/zengtong_paddle/lib/python3.9/site-packages/paddle/fluid/libpaddle.so

    from . import libpaddle
ImportError: libpython3.9.so.1.0: cannot open shared object file: No such file or directory

测试了 Python 3.9, Python 3.10 版本，都会出现类似错误。

nvcc 版本：

Cuda compilation tools, release 11.6, V11.6.55
Build cuda_11.6.r11.6/compiler.30794723_0

Pytorch 安装 cudatoolkit=11.6 版本可以正常运行。

可以通过把 libpython3.9.so.1.0 这个文件复制到 /usr/lib 目录临时解决 libpython3.9.so.1.0 这个文件在 /your/anaconda_home/envs/your_environment_name/lib 目录下 cp /your/anaconda_home/envs/your_environment_name/lib/libpython3.9.so.1.0 /usr/lib

I got the same error. Exactly the same.

Get same error in Python3.9 both conda install and pip install

这个问题在 2.4.2 下依然存在。 我猜测原因大概率是 libpaddle.so 的 RPATH 设置不对，缺少 $ORIGIN/../lib/。 https://docs.conda.io/projects/conda-build/en/stable/resources/use-shared-libraries.html
