tensorflow-gpu is not working with Blas GEMM launch failed

Question

I installed tensorflow-gpu to run my tensorflow code on my GPU. But I can't make it run. It keeps on giving the above mentioned error. Following is my sample code followed by the error stack trace:

import tensorflow as tf
import numpy as np

def check(W,X):
    return tf.matmul(W,X)


def main():
    W = tf.Variable(tf.truncated_normal([2,3], stddev=0.01))
    X = tf.placeholder(tf.float32, [3,2])
    check_handle = check(W,X)
    with tf.Session() as sess:
        tf.initialize_all_variables().run()
        num = sess.run(check_handle, feed_dict = 
            {X:np.reshape(np.arange(6), (3,2))})
        print(num)
if __name__ == '__main__':
    main()

My GPU is pretty good GeForce GTX 1080 Ti with 11 GB vram and there is nothing else significant running on it(just chrome) as you can see in the nvidia-smi :

To add to it, my previous installation of tensorflow cpu worked pretty well. Any help is appreciated. Thanks!

Note- I have cuda-8.0 with cudnn-5.1 installed and their paths added in my bashrc profile .

Answer 1

I had a very similar problem. For me it coincided with an nvidia driver update. So I though it was a problem with the driver. But changing the driver had no effect. What eventually worked for me was cleaning out the nvidia cache:

sudo rm -rf ~/.nv/

Found this suggestion in the NVIDIA developer forum: https://devtalk.nvidia.com/default/topic/1007071/cuda-setup-and-installation/cuda-error-when-running-matrixmulcublas-sample-ubuntu-16-04/post/5169223/

I suspect that during the driver update there where still some compiled files of the old version that were not compatible, or even that were corrupted during the process. Assumptions aside, this solved the problem for me.
