在jupyter noteb中使用ldu PRELOAD

Question

我想在我的系统（Linux 2.6.32_1-18-0-0 x86_64 GNU/Linux）中安装tensorflow库，但是由于系统中的libc太旧，一些函数定义找不到。错误信息如下：

$ python
>>> import tensorflow
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/root/.jumbo/lib/python2.7/site-packages/tensorflow/__init__.py", line 23, in <module>
    from tensorflow.python import *
  File "/root/.jumbo/lib/python2.7/site-packages/tensorflow/python/__init__.py", line 48, in <module>
    from tensorflow.python import pywrap_tensorflow
  File "/root/.jumbo/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow.py", line 28, in <module>
    _pywrap_tensorflow = swig_import_helper()
  File "/root/.jumbo/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow.py", line 24, in swig_import_helper
    _mod = imp.load_module('_pywrap_tensorflow', fp, pathname, description)
ImportError: /root/.jumbo/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so: symbol memcpy, version GLIBC_2.14 not defined in file libc.so.6 with link time reference

因此，我自己实现了缺少的函数，并将其编译为So，放入/home/tensorflow/mylibc中/我的Libc.so在

下次启动python时，我是这样做的

^{pr2}$

在我更多的测试中，一切似乎都很好，实际上也没问题。在

但是，当运行jupyter（ipython notebook）时，在笔记本中，当我输入“import tensorflow”时，我再次遇到导入错误 我运行jupyter如下：

LD_PRELOAD=/home/tensorflow/mylibc/mylibc.so  jupyter notebook --ip=0.0.0.0 --port=8888 > /dev/null 2>&1 &

错误如下

ImportError: /root/.jumbo/opt/gcc46/lib64/libstdc++.so.6: version `GLIBCXX_3.4.19' not found (required by /root/.jumbo/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so)

然后，我决定为python编写一个shell脚本。如下所示：

$ cd ~/.jumbo/bin # the python binary directory
$ ls -l | grep python
-rwxr-xr-x 1 root root      234 Oct 10 03:58 ipython
-rwxr-xr-x 1 root root      234 Oct 10 03:58 ipython2
-rwxr-xr-x 1 root root       87 Oct 10 05:40 python -> python2
lrwxrwxrwx 1 root root       14 Aug 15 02:42 python-config -> python2-config
lrwxrwxrwx 1 root root        9 Aug 15 02:42 python2 -> python2.7
lrwxrwxrwx 1 root root       16 Aug 15 02:42 python2-config -> python2.7-config
-rwxr-xr-x 1 root root     9864 Jul 26 03:17 python2.7
-rwxr-xr-x 1 root root     1626 Jul 26 03:17 python2.7-config
$ rm python
$ vim python # I typed the following text into file python, making python as a wrapper for python2.7, the actual executable file
#!/bin/sh
LD_PRELOAD=/home/tensorflow/mylibc/mylibc.so "/root/.jumbo/bin/python2.7" $@

$ chmod +x python

然后我再次运行jupyter，创建了一个新的笔记本，试图导入tensorflow。但是，又出现了同样的导入错误。在

我列出了jupyter的进程，发现在启动一个新的笔记本时，jupyter实际上会产生一个单独的进程。用python2.7代替python来执行新的笔记本

root       792  0.1  0.0 685252 43856 ?        Ssl  06:31   0:00 /root/.jumbo/bin/python2.7 -m ipykernel -f /root/.local/share/jupyter/runtime/kernel-d8e49d7b-d36f-4806-8013-be5a7c3a2028.json
root      1020  0.5  0.0  13352  1348 ?        S    06:58   0:00 /bin/sh /root/.jumbo/bin/python /root/.jumbo/bin/jupyter-notebook --ip=0.0.0.0 --port=8888

所以，我的问题是，如何让ldu PRELOAD在我的jupyter笔记本上实际工作？谢谢你的建议。在
