We are running Jupyter application hosted on container(with base OS - ubuntu) on a VM server(CentOS). The GPU configuration seems fine as nvidia-smi and nvcc --version is working both on VM and as well as on container. But when I try the below block on jupyter, it’s returning ‘false’.

I am using TensorFlow commands to check GPU availability and its functionality.

```python
import tensorflow as tf
tf.test.is_gpu_available()
tf.test.is_built_with_cuda()

```

Calling those last 2 functions provides with “false”.

If anyone can give me any directions regarding this, I would really appreciate it!

GPU support must be enabled when Tensorflow is built. You’re using a CPU-only build of Tensorflow, as indicated by the second function you called.

If you’re using conda, install tensorflow-gpu or tensorflow-gpu-base.

Hi rolweber!

Thanks for the response! I’ve got tensorflow-gpu 1.14.0, same version as that of tensorflow. Its installed but I still am getting that error. Do I have to use tensorflow-gpu instead of tensorflow in that above code that I’ve posted to make it work?

Restarting the kernel, solved it for me.  
If its still not solved try rebooting the system.

My issue was with .env file which had CUDA\_VISIBLE\_DEVICES=XXXX. Once removed, the Jupyter notebook could access the GPUs.
