Cannot run any tensorflow files after install [URGENT] about tf-coriander

[hughperkins]

change to a different directory :-) You cant run python from the source tree.

[tgs266]

The problem is that I am not in the source directory. I am in the home directory, running "python" in the terminal, then trying to import tensorflow. Even if I try to go into another folder like Documents or Downloads it doesn't work

[hughperkins]

Ah, hmmm, right. Seems like it cant import the version of libstdc++ that its expecting. What answers did you give to the questions about python paths, when you did ./configure in tensorflow?

[tgs266]

I never did ./configure. Nothing about that came up during installation. All I did was run the wheel file

[tgs266]

I am trying to install from source right now to see if it changes anything

[hughperkins]

Ah. Installing from source sounds like a good plan. Or using a binary that was built against the exact same version of anaconda you are using.

Ok I think I found one of the problems... I am not running OpenCL 1.2+ I am on 1.1. I have been googling for about and hour now with no luck. Do you know how to update opencl on ubuntu 16.04?

[hughperkins]

What do you mean by 'running OpenCL 1.2'? Normally, your system doesnt realy have an opencl version as such, I think. The GPU driver is what has an OpenCL version. What is the output of running:

sudo apt-get install clinfo
clinfo

?

    NOTE:   your OpenCL library declares to support OpenCL 1.2,
        but it seems to support up to OpenCL 2.1 too.

Also my gpu is r9 270x

[hughperkins]

Oh, Clover...

Soo....

Clover is an opensource driver, but it's OpenCL 1.1 as you see. Except it's not, because it doesnt support basic maths like tanh.

You can choose to try using Clover, but I dont support 1.1 for now: you'd need to hack around in the code, adding shims and stuff. This is hard.

On the whole, if you prefer 'easy' to 'hard', you might consider installing the proprietary AMD drivers.

[hughperkins]

(Note that the AMD driver for 270x supports 1.2: https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units )

[tgs266]

Ok. I am going to have to look around a little for a driver that is compatible with both the 270x and 16.04... There is a chance I am just going to have to roll back ubuntu to 14.04 or 15 which is going to be a pain to do. Thanks for your help
