ImportError: libpython3.7m.so.1.0: 无法打开共享对象文件：没有那个文件或目录。

Question

我在计算集群上运行Python脚本遇到了问题，如果这是一个天真的错误，请提前向您道歉。我不确定问题是否源于我错误地配置了自己的conda虚拟环境，但无论如何，当我运行以下命令时都会重现问题：

srun -p use-everything --pty python test.py

我遇到了错误。

在我的本地机器上，当我运行虚拟环境时，也遇到了同样的问题，我通过 sudo apt-get install libpython3.7 简单地解决了这个问题。

以下是其他可能有帮助的信息。

$which libpython
/usr/bin/which: no libpython in (/om2/user/armas/anaconda/envs/dist_rl/bin:/om2/user/armas/anaconda/bin:/om2/user/armas/anaconda/condabin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin)

$echo $PATH
/om2/user/armas/anaconda/envs/dist_rl/bin:/om2/user/armas/anaconda/bin:/om2/user/armas/anaconda/condabin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin

$echo $LD_LIBRARY_PATH
/om2/user/armas/anaconda/bin/

当我更改我的LD_LIBRARY_PATH时，即export LD_LIBRARY_PATH=/om2/user/armas/anaconda/lib:$LD_LIBRARY_PATH并运行脚本时，我的anaconda认为我没有安装jax。我运行了pip install dm-acme[jax]，现在当我运行脚本时，它会说我没有名为atari_py的模块。我认为这将引导我进入依赖链。

我使用此链接安装acme，但是使用了conda环境。我的系统管理员说这可能是因为acme不适用于anaconda。如果是这种情况，为什么会这样？

如果我遗漏了任何信息，请让我知道，并确保添加，再次感谢！

两件可能有帮助的事情：（1）您能否给我们提供“ImportError”行的完整错误回溯？（2）您能否告诉我们test.py中运行的代码类型是什么？对我来说，它看起来有点像在不同环境中编译的扩展模块，现在在错误的环境中执行。顺便说一句：您的诊断中有几件奇怪的事情：“which libpython”不起作用 - “which”只会找到可执行文件而不是库。“$echo $LD_LIBRARY_PATH”应该打印库目录的路径（例如“/om2/user/armas/anaconda/lib”），而不是“bin”。 - cel

你好，我已经更新了这篇文章。请告诉我您的想法，谢谢！ - Alejandro Armas

我在虚拟环境中使用DearPyGui时遇到了同样的问题，这个解决方案确实可行。我必须在CMD提示符中从虚拟环境中运行apt-get以安装所需的库。 - khazaddim

试一下这个：

sudo apt-get install libpython3.7
