我正在研究一些使用GDAL(http://www.gdal.org/)及其python绑定从ECW文件中提取图像数据的python代码。 GDAL是从源代码构建的,以获得ECW支持。
该程序在我进入的群集服务器上运行。我已经通过ssh终端测试了程序,运行正常。但是,我现在想使用qsub向集群提交作业,但它会报告以下内容:
Traceback (most recent call last):
File "./gdal-test.py", line 5, in <module>

_mod = imp.load_module('_gdal', fp, pathname, description)
ImportError: /mnt/aeropix/prgs/.local/lib/libgdal.so.1: undefined symbol: H5Eset_auto2
我做了一些挖掘并尝试使用LD_DEBUG=symbols
来尝试找出差异所在的地方,但就我的知识/理解而言,这是关于我的。
供参考,以下是LD_DEBUG=symbols
并在ssh终端中运行代码(通过grep H5Eset_auto2
管道以减少部分输出)所发生的情况:

我想我不确定为什么当使用qsub提交时,它似乎停止查看libgdal.so.1,当它继续在终端中运行时看起来。我还注意到qsub作业能够正确找到libhdf5.so.7
(它应该找到H5Eset_auto2
的位置),因为它可以找到不同的符号H5Eprint

16915: symbol=H5Eprint; lookup in file=/mnt/aeropix/prgs/.local/lib/libhdf5.so.7 [0]
在此阶段,任何关于此的指示都将非常有用(我希望有足够的信息 - 我非常乐意提供更多信息,我不知道还有什么可能是在这个阶段很有用。)
编辑:
/usr/bin
的内容似乎与使用qsub
提交的作业不同(特别是libtool
缺失)。正在调查中。
答案 0 :(得分:22)
经过两十条评论来了解情况之后,发现libhdf5.so.7
实际上是一个符号链接(有几个间接级别)到一个不是的文件在排队的进程和交互式进程之间共享。这意味着即使符号链接本身位于共享文件系统上,文件的内容也不会,因此进程看到了不同版本的库。
为了将来参考:除了检查LD_LIBRARY_PATH
之外,最好使用nm -D
检查库以查看符号是否确实存在。在这种情况下,发现它们确实以交互模式存在,但在队列中运行时不存在。快速md5sum
显示文件实际上是不同的。
