我一直在使用Singularity 2.6并且最近将我的Singularity升级到3.0（由于技术原因我无法升级到3.0.3）。使用Singularity 3.0我使用与用于使用Singularity 2.6构建容器的完全相同的定义文件构建我的新容器。从那以后，我再也无法可靠地运行NVIDIA FleX并且偶尔会出现以下错误。在过去10个月左右的时间里，我的NVIDIA FleX代码中没有任何改动，我几乎每天都在运行FleX，从来没有遇到过这样的问题。我想知道，问题可能是什么，试图说错误是什么？我可能做错了什么或需要改变以防止这种情况发生？
基于我在代码中添加的print语句，我所知道的是当我在FleX代码中调用UnmapBuffers（）函数时会发生这种情况。但是自从我编写这段代码以来，我一直这样做，从来没有遇到任何问题。虽然这可能不是很有帮助，但这是函数的作用：

对于Singularity用户：不幸的是，我不能再尝试使用Singularity 2.6来查看问题是否消失，因为我使用的是集群而无法自行安装。
请注意，我在构建它时将NVIDIA的Docker镜像放入容器中。这是构建容器时Singularity定义文件的主要部分：

事实证明我的代码试图在模拟过程中在磁盘上创建一个文件，并且文件由于某种原因不会被创建，这可能与this有关。代码总是在过去工作但我不知道我的容器中发生了什么变化导致代码的那部分无法再创建该文件。
