我正试图用Ubuntu在Linux服务器上运行一个python(.py(文件。我用python3.8 -m venv env_name创建了一个虚拟环境，并安装了no，这是该文件的一个依赖项。我在虚拟环境中使用了pip3 install theano=="1.0.5"，它安装得很好。然而，在尝试导入包时，我收到了以下错误：
raise Exception('Compilation failed (return status=%s): %s' %
Exception: Compilation failed (return status=1): /usr/bin/ld: /usr/local/lib/libpython3.8.a(abstract.o): relocation R_X86_64_PC32 against symbol `PyObject_SetItem' can not be used when making a shared object; recompile with -fPIC. /usr/bin/ld: final link failed: Bad value. collect2: error: ld returned 1 exit status.
我之所以使用theano==1.0.5，是因为我使用的代码结构在这个版本的Windows 10和Python 3.8中运行得很好。
如何解决此错误并导入该o？
编辑：执行import theano时错误消息的整个Traceback是：

您的错误是说theano在您的系统上找不到lazyliner的版本。在Ubuntu服务器上安装sudo apt-get install python3-dev，以安装theano所需的开发头文件和其他头文件。
