Aborting. error: exception occurred: Subprocess aborted这个错误是在虚拟机中安装遇到的问题似乎是显卡映射的问题暂时并没有解决。在物理机没有遇到此问题。3、paraview启动提示HDF5 版本问题这个造成这个问题主要是因为环境变量的问题系统的HDF5版本与pylith的HDF5版本相互冲突引发的错误。Warning! ***HDF5 library release mismatched error*** The HDF5 header files used to compile this application are not compatible with the version used by the HDF5 library to which this application is linked. Data corruption or segmentation faults may occur if the application continues. This can happen when an application was compiled by one version of HDF5 but linked with an incompatible version of static or shared HDF5 library. You should recompile the application or check your shared library related settings such as LD_LIBRARY_PATH. You can, at your own risk, disable this warning by setting the environment variable HDF5_DISABLE_VERSION_CHECK to a value of 1. Setting it to 2 or higher will suppress the warning messages totally. Headers are 1.14.2, library is 1.14.0 Bye... error: exception occurred: Subprocess aborted**1 在配置 pylith 的时候设置了环境变量#************注意user修改为自己的用户名**************# python pylith......exportLD_LIBRARY_PATH$pylith/lib:$pylith/lib64只需要注释掉LD_LIBRARY_PATH的变量设置即可解决问题。#************注意user修改为自己的用户名**************# python pylith......# export LD_LIBRARY_PATH$pylith/lib:$pylith/lib64注意注意注意**2 paraview 与 pylith 一块使用时两个软件的HDF5会相互干扰在本例中paraview使用的是 1.14.2 而 pylith 使用的版本为 1.14.0 所以为了解决这个问题我删除掉了pylith/lib文件夹下的所有的HDF5库文件然后在环境变量中将环境变量改为#************注意user修改为自己的用户名**************# python pylith......exportLD_LIBRARY_PATH$pylith/lib:$pylith/lib64:opt/Paraview-5.12/lib这样 pylith 在运行计算时也会使用paraview的高版本的DHF5这样得到的结果文件使用paraview打开也不会出现斑纹不对应的问题。注意注意注意########想一劳永逸就执行下面操作不需要修改环境变量**1和**2步骤当然由于HDF5版本引起的问题也可以通过将paraview中或者pylith中高版本的HDF5拷贝到另一个软件的bin目录中这样的话不需要修改环境变量就可以解决这个问题。相对应的HDF5文件在相应软件的lib或者lib64文件夹中。 4、paraview启动缺少模块 ‘encodings’Python path configuration: PYTHONHOME/home/aduser/pylithPYTHONPATH/home/aduser/pylith/lib/python3.10/site-packages:/home/aduser/pylith/lib64/python3.10/site-packagesprogram name/usr/bin/python3isolated0environment1user site1importsite1sys._base_executable/usr/bin/python3sys.base_prefix/home/aduser/pylithsys.base_exec_prefix/home/aduser/pylithsys.executable/usr/bin/python3sys.prefix/home/aduser/pylithsys.exec_prefix/home/aduser/pylithsys.path[/home/aduser/pylith/lib/python3.10/site-packages,/home/aduser/pylith/lib64/python3.10/site-packages,/home/aduser/pylith/lib/python38.zip,/home/aduser/pylith/lib/python3.8,/home/aduser/pylith/lib/python3.8/lib-dynload,]Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding Python runtime state: core initialized ModuleNotFoundError: No module namedencodingsCurrent thread 0x00007f5e3480b740(most recent call first):no Python frame出现这个问题大概率存在两个问题第一你要检查你的启动命令是否是“paraview”第二检查你的pylith、Python以及paraview的环境变量设置是否正确。5、paraview使用附加在使用paraview读取Python脚本显示成果时会由于Python脚本中的相对路径报错错误显示为找不到文件解决方案即将相对路径更改为绝对路径。

Use QT_QPA_PLATFORMwayland to run on Wayland anyway. libGL error: MESA-LOADER: failed to open vmwgfx: /usr/lib/dri/vmwgfx_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri) libGL error: failed to load driver: vmwgfx libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri) libGL error: failed to load driver: swrast ( 0.963s) [paraview ]vtkXOpenGLRenderWindow.:653 ERR| vtkXOpenGLRenderWindow (0x2a0f0b0): Cannot create GLX context. Aborting. error: exception occurred: Subprocess aborted这个错误是在虚拟机中安装遇到的问题似乎是显卡映射的问题暂时并没有解决。在物理机没有遇到此问题。3、paraview启动提示HDF5 版本问题这个造成这个问题主要是因为环境变量的问题系统的HDF5版本与pylith的HDF5版本相互冲突引发的错误。Warning! ***HDF5 library release mismatched error*** The HDF5 header files used to compile this application are not compatible with the version used by the HDF5 library to which this application is linked. Data corruption or segmentation faults may occur if the application continues. This can happen when an application was compiled by one version of HDF5 but linked with an incompatible version of static or shared HDF5 library. You should recompile the application or check your shared library related settings such as LD_LIBRARY_PATH. You can, at your own risk, disable this warning by setting the environment variable HDF5_DISABLE_VERSION_CHECK to a value of 1. Setting it to 2 or higher will suppress the warning messages totally. Headers are 1.14.2, library is 1.14.0 Bye... error: exception occurred: Subprocess aborted**1 在配置 pylith 的时候设置了环境变量#************注意user修改为自己的用户名**************# python pylith......exportLD_LIBRARY_PATH$pylith/lib:$pylith/lib64只需要注释掉LD_LIBRARY_PATH的变量设置即可解决问题。#************注意user修改为自己的用户名**************# python pylith......# export LD_LIBRARY_PATH$pylith/lib:$pylith/lib64注意注意注意**2 paraview 与 pylith 一块使用时两个软件的HDF5会相互干扰在本例中paraview使用的是 1.14.2 而 pylith 使用的版本为 1.14.0 所以为了解决这个问题我删除掉了pylith/lib文件夹下的所有的HDF5库文件然后在环境变量中将环境变量改为#************注意user修改为自己的用户名**************# python pylith......exportLD_LIBRARY_PATH$pylith/lib:$pylith/lib64:opt/Paraview-5.12/lib这样 pylith 在运行计算时也会使用paraview的高版本的DHF5这样得到的结果文件使用paraview打开也不会出现斑纹不对应的问题。注意注意注意########想一劳永逸就执行下面操作不需要修改环境变量**1和**2步骤当然由于HDF5版本引起的问题也可以通过将paraview中或者pylith中高版本的HDF5拷贝到另一个软件的bin目录中这样的话不需要修改环境变量就可以解决这个问题。相对应的HDF5文件在相应软件的lib或者lib64文件夹中。 4、paraview启动缺少模块 ‘encodings’Python path configuration: PYTHONHOME/home/aduser/pylithPYTHONPATH/home/aduser/pylith/lib/python3.10/site-packages:/home/aduser/pylith/lib64/python3.10/site-packagesprogram name/usr/bin/python3isolated0environment1user site1importsite1sys._base_executable/usr/bin/python3sys.base_prefix/home/aduser/pylithsys.base_exec_prefix/home/aduser/pylithsys.executable/usr/bin/python3sys.prefix/home/aduser/pylithsys.exec_prefix/home/aduser/pylithsys.path[/home/aduser/pylith/lib/python3.10/site-packages,/home/aduser/pylith/lib64/python3.10/site-packages,/home/aduser/pylith/lib/python38.zip,/home/aduser/pylith/lib/python3.8,/home/aduser/pylith/lib/python3.8/lib-dynload,]Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding Python runtime state: core initialized ModuleNotFoundError: No module namedencodingsCurrent thread 0x00007f5e3480b740(most recent call first):no Python frame出现这个问题大概率存在两个问题第一你要检查你的启动命令是否是“paraview”第二检查你的pylith、Python以及paraview的环境变量设置是否正确。5、paraview使用附加在使用paraview读取Python脚本显示成果时会由于Python脚本中的相对路径报错错误显示为找不到文件解决方案即将相对路径更改为绝对路径。
