Problems and solutions in installing tf on Redhat

[jinfengfeng]

I encountered several problems in installing tensorflow on Redhat system. I solved them by googling solutions. Hope my experience may be helpful to some users.

OS version: Red Hat Enterprise Linux Server release 6.2 (Santiago)
Linux kernel: 2.6.32-220.el6.x86_64

Problems and solutions:

1. glibc version is too low

Install higer version glibc, e.g. glibc-2.17.
Please use at least version 2.17. You can configure the installation using --prefix option to specify the path to install, and then modify LD_LIBRARY_PATH to include the new glibc library.

2. link problem after install higher version of glibc

Error info looks like:
"
error while loading shared libraries: __vdso_time: invalid mode for dlopen():Invalid argument
"
You need to use the following method to run a program (eg. python):
/path/to/glibc-2.17/lib/ld-linux-x86-64.so.2 --library-path /path/to/glibc-2.17/lib:$LD_LIBRARY_PATH:/path/to/gcc-5.2.0/lib64:/usr/lib64/ /path/to/anaconda/bin/python2.7

3. numpy version problem

Install new version of numpy using pip.

4. protobuf3 not found, and
Error in python after 'import tensorflow': TypeError: init() got an unexpected keyword argument 'syntax'

pip install 'protobuf>=3.0.0a3'

5. failed call to cuInit: CUDA_ERROR_NO_DEVICE
Explicitly specify a cuda device in you environment variable:
export CUDA_VISIBLE_DEVICES=0

6. libcuda.so.1 not found

Explicitly specify the path of this lib in your LD_LIBRARY_PATH environment variable.
libcuda.so is in usually in /usr/lib64

7. ELFCLASS32 error
elf is incorrect, should use a 64-bits .so file (usually in */lib64)

8. glibc 2.15 cannot create regular file `/var/db/Makefile': Permission denied
Use glibc 2.17 or even higher version.

Thanks, @jinfengfeng .

@jinfengfeng I can not understand the second point 2. link problem after install higher version of glibc in your above solution. How to solve this error:
while loading shared libraries: __vdso_time: invalid mode for dlopen():Invalid argument
?

@jinfengfeng I did not understand Point 2 either, could you please help. @IvyGongoogle Were you able to solve the issue?

I tried what was mentioned in point 2, but running a command like
/opt/glibc-2.17/lib/ld-linux-x86-64.so.2 --library-path /opt/glibc-2.17/lib:$LD_LIBRARY_PATH:usr/lib64/ /home/njafer/python/bin/python3 at least works, but a command like
/opt/glibc-2.17/lib/ld-linux-x86-64.so.2 --library-path /opt/glibc-2.17/lib:$LD_LIBRARY_PATH:usr/lib64/ ls gives me a
ls: error while loading shared libraries: ls: cannot open shared object file

@naveenjafer
To run ls, you may need something like

/opt/glibc-2.17/lib/ld-linux-x86-64.so.2 --library-path /opt/glibc-2.17/lib:$LD_LIBRARY_PATH:usr/lib64/ /bin/ls
