Sorry for an inappropriate question.First time installed tensor-flow.While testing if it was installed correctly getting errors/warning in tf.Session().
using python 3.5.
Code
import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))

Problem: I followed Microsoft's instruction in order to properly install and run TensorFlow 2 in WSL with GPU acceleration, using DirectML (here's the document).
Following the installation, when I try and import tensorflow in Python I get the following output:
>>> import tensorflow
2022-11-22 15:52:33.090032: I tensorflow/core/platform/cpu_feature_guard.cc:193]

I tried instead to follow the instructions for TensorFlow 1 and PyTorch (just in case something was wrong with my machine) and they both work perfectly, so I assume this issue only involves TensorFlow 2 somehow.
Did anyone encounter the same problem?
Thanks to everybody in advance :)

Had the same problem, and downgrading TensorFlow from 2.11 fixed it. First remove the existing version:
pip uninstall tensorflow-cpu
Then re-install, this time with 2.10.0:
pip install tensorflow-cpu==2.10.0
After that, try importing it in Python. You should see something like the following (apologies for the messy output):
>>> import tensorflow as tf

You can test that it works by adding two tensors. Running a command like the following:
print(tf.add([1.0, 2.0], [3.0, 4.0]))
And somewhere in the output, you should be able to verify that DirectML has found your GPU:

I'm attempting to do text generation with Tensorflow but whenever I run it I get this:

what could be wrong?
EDIT 1
The code works if I only use the CPU, I've reinstalled CUDA but it didn't help.
I installed TensorFlow 2.8.0 in my Windows 10 PC with CPU only. No Nvidia/CUDA hardware/software installed at all. I run a simple Python image processing project with CNN and I got bunch of no sense messages:

Why I'm getting these CUDA messages? I never installed anything for CUDA. I did try the following like everyone recommended in Google:
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'
And still getting these messages. WHY? I really don't want to see any CUDA message because I did not install nothing for it. This is very bad for the TensorFlow deployment team. Why no one test this before in Windows?
I'm waiting for any suggestion to fix this TensorFlow installation issues.
is the min log before the first import of tensorflow in the project? if i move the min log under the import tensorflow i will get the warnings you get
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3' # removes tf informative messages
import tensorflow as tf # noqa E402
print(tf.__version__)

I configured tensorflow to work with CUDA support on my GPU (GeForce 840M) but the programs are running quite slow in compare to what my CPU used to earlier. Also, I do not get any kind of message that the so and so CUDA library was successfully opened when I run the program. Instead, this is what I get in logs when I run any tensorflow program:

And so on the program started runnning but it didn't ran any faster according to my expectations. I installed CUDA from the official documentation, but I did not reset the git master head since it was creating issues and I used the same optimization flags provided bazel build -c opt --config=cuda //tensorflow/tools/pip_package:build_pip_package when building through bazel.
Did you use nvidia-smi to tell whether you have the right cuda drivers installed and that your gpu is visible to the system?
In TF you can set the log_device_placement option to understand if any ops are being assigned to the GPU.
