Why can I not import tensorflow into my Jupyter notebook?

I have run a simple neural network through pycharm, pointing it to a conda virtual environment with tensorflow and dependencies installed. When I launch a jupyter notebook from that same env the exact code aborts when I try and import tensorflow.
This is the code at the top of the notebook:
import tensorflow as tf
from tensorflow import keras
.....
I expected tensorflow and keras to load ok.
Instead I got:
`---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-3-2be7691b079e> in <module>
----> 1 import tensorflow as tf
2 from tensorflow import keras
...
ModuleNotFoundError: No module named 'tensorflow'
I added a line to list installed modules at the top of the notebook in case it was looking somewhere without tensorflow installed :
!conda list
`
And got:
# packages in environment at /home/user/anaconda3/envs/tf-cert:
#
# Name Version Build Channel

cudnn 8.2.1 cuda11.3_0

I faced a similar problem while using VS Code. I had created a virtual environment using venv, but when I selected that environment, I wasn't able to import any libraries even though I had installed all the required ones.
I simply deleted the environment and created a new one using -
conda create --prefix ./env pandas numpy ... in the terminal/command prompt. I then restarted VS Code and selected this particular environment. That fixed the issue. The python version and the library versions need to be in sync with each other to work properly. Hope this works for you too.
Edit:
I was again facing the same problem when I created a new environment. I then selected the python environment where I had installed the Tensorflow library from the top right corner in Jupyter notebook (underlined red). That solved the issue!

Why does Anaconda install pytorch cpuonly when I install cuda?

I have created a Python 3.7 conda virtual environment and installed the following packages using this command:
conda install pytorch torchvision torchaudio cudatoolkit=11.3 matplotlib scipy opencv -c pytorch
They install fine, but then when I come to run my program I get the following error which suggests that a CUDA enabled device is not found:
raise RuntimeError('Attempting to deserialize object on a CUDA '
RuntimeError: Attempting to deserialize object on a CUDA device but torch.cuda.is_available() is False. If you are running on a CPU-only machine, please use torch.load with map_location=torch.device('cpu') to map your storages to the CPU.
I have an NVIDIA RTX 3060ti GPU, which as far as I am aware is cuda enabled, but whenever I go into the Python interactive shell within my conda environment I get False when evaluating torch.cuda.is_available() suggesting that perhaps CUDA is not installed properly or is not found.
When I then perform a conda list to view my installed packages:

There seems to be a lot of things saying cpuonly, but I am not sure how they came about, since I did not install them.
I am running Ubuntu version 20.04.4 LTS

I ran into a similar problem when I tried to install Pytorch with CUDA 11.1. Although the anaconda site explicitly lists a pre-built version of Pytorch with CUDA 11.1 is available, conda still tries to install the cpu-only version. After a lot of trial-and-fail, I realize that the packages torchvision torchaudio are the root cause of the problem. So installing just PyTorch would fix this:
conda install pytorch cudatoolkit=11.1 -c pytorch -c nvidia

You can ask conda to install a specific build of your required package.pytorch builds supporting cuda have the phrase cuda somewhere in their build string, so you can ask conda to match that spec. For more information, have a look at conda's package match spec.
$ conda install pytorch=*=*cuda* cudatoolkit -c pytorch

I believe I had the following things wrong that prevented me from using Cuda. Despite having cuda installed the nvcc --version command indicated that Cuda was not installed and so what I did was add it to the path using this answer.
Despite doing that and deleting my original conda environment and using the conda install pytorch torchvision torchaudio cudatoolkit=11.3 matplotlib scipy opencv -c pytorch command again I still got False when evaluating torch.cuda.is_available().
I then used this command conda install pytorch torchvision torchaudio cudatoolkit=10.2 matplotlib scipy opencv -c pytorch changing cudatoolkit from verison 11.3 to version 10.2 and then it worked!
Now torch.cuda.is_available() evaluates to True
Unfortunately, Cuda version 10.2 was incompatible with my RTX 3060 gpu (and I'm assuming it is not compatible with all RTX 3000 cards). Cuda version 11.0 was giving me errors and Cuda version 11.3 only installs the CPU only versions for some reason. Cuda version 11.1 worked perfectly though!
This is the command I used to get it to work in the end:
pip install torch==1.9.0+cu111 torchvision==0.10.0+cu111 torchaudio==0.9.0 -f https://download.pytorch.org/whl/torch_stable.html

If there is nothing wrong with your nvidia driver setup, maybe you are missing nvidia channel from installation arguments. The pytorch documentation helped me generate this command that eventually solved my problem:
conda install pytorch torchvision torchaudio pytorch-cuda=11.6 -c pytorch -c nvidia

Installing jupyter inside conda's virtual environment solve my issue. I was having the same issue, even pytorch with cuda is installed and !nvidia-smi showing GPU , but while trying to access jupyter notebook , it was showing only cpu.
While I was trying from command line torch is finding CUDA but from jupyter is not showing, So I just pip install jupyter on virtual environment of conda and after that problem is solved .

Use the exact script from the Pytorch website works for me:
conda install pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 cudatoolkit=10.2 -c pytorch
But if I use
conda install pytorch==1.12.1 torchvision==0.13.1 cudatoolkit=10.2 -c pytorch
no installing torchaudio, it will install cpu versions of pytorch and torchvision. I found it interesting and don't know why.

Error installing tensorflow-io kaggle notebook

I'm trying to install tensorflow-io to work with flac audio files
For that I use this command pip install -q tensorflow-io
But I got this Error:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

How to install tensorflow-io on kaggle notebook

I think it's only a warning. I got the same somedays back when I did
!pip install tensorflow-io
It got installed successfully and I was able to train also.

No module named 'tensorflow_probability'

I need to use Tensorflow and Tensorflow_Probability. After installing it by these commands: conda install tensorflow-probability or pip install --upgrade tensorflow-probability , I ran it in the notebook:
import tensorflow_probability as tfp
but it returns this error:
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-8-41494c8c96ff> in <module>
----> 1 import tensorflow_probability as tfp
ModuleNotFoundError: No module named 'tensorflow_probability'.
The results of
pip list
is as below (related parts):
tblib 1.3.2
tensorboard 1.13.1
tensorflow 1.13.1
tensorflow-estimator 1.13.0
tensorflow-probability 0.7.0
termcolor 1.1.0
terminado 0.8.1
testpath 0.4.2
tfp-nightly 0.8.0.dev20190708
Theano 1.0.4
toolz 0.9.0
Can anyone help me to solve this problem (I am using Win 10)?

Your versions are correct and your command is correct too.
Seems like inconsistency in other module is causing this.
run the following commands and try again:
pip install -U dm-sonnet==1.23
pip install --upgrade tfp-nightly

https://github.com/deepmind/graph_nets/issues/3
https://github.com/tensorflow/probability/issues/103

tensorflow-probability 0.7.0
is not compatible with:
tensorflow 1.13.1
check the tensoflow-probability version release page https://github.com/tensorflow/probability/releases
Correct solution will be either to upgrade tensorflow to 1.14.0 or downgrade tensorflow-probability to 0.6.0
pip install -U tensorflow-probability==0.6.0

As the previous answer, you have to find a version compatible with your TensorFlow version through this page: https://github.com/tensorflow/probability/releases
