CUDA Tensorflow 版本，nvidia-smi 版本问题。 获取卷积算法失败。 这可能是因为 cuDNN 初始化失败，

Question

Tried, preds = model.predict(k[np.newaxis,...])

UnknownError: Failed to get convolution algorithm. This is probably because cuDNN failed to initialize, so try looking to see if a warning log message was printed above. [[node model/stem_conv/Conv2D (defined at:3) ]] [Op:__inference_distributed_function_18348]

Hardware: Make: OMEN, OS_ Windows 10, GPU NVIDIA GEFORCE RTX 2060, My System configuration

Seems like some thing is missing. CUDA version is not in Sync is what I guess. Please correct me. If its NVIDIA STUDIO DRIVER not appropriate, Could some one please help me the one appropriate for Tensorflow 2.1.0

Tensor Flow Version: 2.1.0, Keras Version: 2.2.4-tf, Python 3.7.7 (default, May 6 2020, 11:45:54) [MSC v.1916 64 bit (AMD64)],Pandas 1.0.5,Scikit-Learn 0.23.1

Answer 1

I had similar issue. It got fixed after I downgraded CUDA from 11 to 10.1 version ( NVIDIA Link ).

As per TF documentation:

CUDA® Toolkit —TensorFlow supports CUDA 10.1 (TensorFlow >= 2.1.0)

EDIT (more info below):

You can find the compatible driver at: https://www.nvidia.com/en-us/drivers/results/149127/

I use Python 3.7 along with the tensorflow-gpu installed in a conda environment.

NOTE: If you installed TF with pip install tensorflow , it may not have the required python packages for cuda downloaded. I would recommend you uninstall/re-install with:

pip install tensorflow-gpu

Here's my output for a quick test:

import tensorflow as tf
print(tf.__version__)
print(tf.config.experimental.list_physical_devices('GPU'))

2.1.0
[PhysicalDevice(name='/physical_device:GPU:0', device_type='GPU')]

For your reference:

nvidia-smi
