Describe the problem
A similar issue as to #46606, #43193, and #45055. When attempting to run python -c "import tensorflow as tf;print(tf.reduce_sum(tf.random.normal([1000, 1000])))"
, I get the following trace;

Provide the exact sequence of commands / steps that you executed before running into the problem
I continue to get the above issue despite following the steps and suggestions in each of the other similar issues.
I tried adding the environmental variables through cmd, which wasn’t mirrored in the GUI so I added them there as well. This did not fix the issue.
I re-installed the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, and 2019. This did not fix the issue.
I enabled long paths. This did not fix the issue.
I was already on a 64bit release of Python 3.8.8, which the venv I’m using was created with.
I’ve restarted the terminal and restarted my PC several times, which did not fix the issue.
I created the C:\tools\cuda folder and extracted the contents of the cuDNN there, and ensured that it was on PATH. This confuses me since it’s not mentioned as a necessity in the installation process of cuDNN itself. Either way, this did not fix the issue.
Any other info / logs deviceQuery running. All the items in PATH. The contents of the CUDA bin folder, showing the supposedly missing files exist.
Thank you in advance for your help.

I was able to get past this error by doing
os.add_dll_directory("C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.2/bin")
before importing tensorflowThanks, it saved my day!
bumping this here because the fix looks like temporary. I did not face this issue using python 3.8 in a virtualenv but occured in system python 3.9 on windows. From the people it also looks like a windows issue. Even though the cuda paths added to path correctly, it still doesn’t recognize the appropriate dll’s.
EDIT
I can confirm the fault is on windows. If you install the python from store, python doesn’t load the path. Install it from python official website.
@karthik-653 Before impoting anything(besides os ofc) should work.
This solution (the answer on the issue) is for PYTHON. THIS IS PYTHON ISSUE. SPECIFICALLY STORE INSTALLED WHATEVER YOUR PYTHON CODE YOU ARE RUNNİNG. ADD THIS TO THE TOP OF THE FILE. E.G. IF YOU ARE RUNNING THE CODE WITH
python main.py
, add below code to top of the main.py fileChange path accordingly with your cuda version.
