CUDA toolkit seems intal but tensorflow don't see GPU

I have a laptop with an RTX3060, I use tensorflow >= 2.6.0 on ubuntu 20.04. I have installed nvidia drivers version 495.44

I installed dependencies following tensorflow tutorial. I have installed cuda 11.5 in /usr/local/cuda-11.5 and cudNN for cuda 11.5 and set path in zshrc.

When I import tensorflow in a program I have no warnings/errors but when I try to list them I have this :

tf.config.list_physical_devices('GPU')

Please make sure the missing libraries mentioned above are installed properly if you would like to use GPU. Follow the guide at https://www.tensorflow.org/install/gpu for how to download and setup the required libraries for your platform.

Does anyone know why tensorflow still don't see my GPU ?

Seems odd to have an include dir in your LD_LIBRARY_PATH, but the libcudnn.so should have been found in the second part -- so where is it? Use locate libcudnn.so to find it. How did you install it?

@ubfan1 I use .deb file from nvidia official website. Yes in fact libcuddn was in /usr/lib/cuda/lib64, I add it to LD_LIBRARY_PATH and it's working.

I sit in a Tesla and translated this thread with Ai:

EN: CUDA toolkit seems intal but tensorflow don't see GPU

TH: ชุดเครื่องมือ CUDA ดูเหมือนจะสมบูรณ์ แต่ tensorflow ไม่เห็น GPU

RO: Setul de instrumente CUDA pare intalnit, dar tensorflow nu vede GPU

RU: Инструментарий CUDA кажется встроенным, но тензорный поток не видит GPU

VI: Bộ công cụ CUDA có vẻ nội bộ nhưng tensorflow không thấy GPU

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
