I have installed Cuda using following command on Anaconda

conda install -c anaconda cudatoolkit

Earlier I also have used following command to install Tensorflow GPU version

conda install -c anaconda tensorflow-gpu

However, Tensorflow-gpu is not activated and when I run the following script:

    from tensorflow.python.client import device_lib
    print(device_lib.list_local_devices())

name: "/device:CPU:0"

device_type: "CPU"

memory_limit: 268435456

If you install numba via anaconda, you can run numba -s which will confirm whether you have a functioning CUDA system or not. On a linux system with CUDA:

$ numba -s
