error when trying to import tensorflow GPU - tensorflow

Question

here's the code that i use to check if tf.gpu is working or not
import tensorflow as tf
if tf.test.gpu_device_name():
print('Default GPU Device:{}'.format(tf.test.gpu_device_name()))
else:
print("Please install GPU version of TF")
and here's the error
Failed to load the native TensorFlow runtime.

Answer 1

To use the GPU with Tensorflow, you must install the gpu version of Tensorflow
python -m pip install tensorflow-gpu
Make sure that you are also using a 64 bit version of python, as it will only work with those parameters.
EDIT:
As of Tensorflow 2.0+, both the CPU and GPU versions of Tensorflow have been packaged together.
To get Tensorflow to work with your GPU, you need to download cuDNN. Depending on what CUDA version you have, you will need to place some header files and some dll files in the file location of where you installed CUDA.
