Answer 1

I faced the same problem at first. I realized that in the conda-->envs --> tensorflow-->Scripts-->idle.exe, is the python 3.5.5 shell. Where you can import tensorflow without any problems. So, I chaged the directory as C:\Users\Temp\Anconda3..... and then activated and deactived the tensorflow once. In the next step I entered the python mode and import tensorflow as tf worked right.

Answer 2

I had the same problem and I think I've found the solution! See, I had installed both CPU and GPU versions of Tensorflow at the same time which apparently is wrong. Then, I uninstalled the GPU version, it didn't work this time either. So I uninstalled both of them and reinstalled the CPU version. It's working now.

BTW I'm on Win10(1803) and python 3.6.5 (not using anaconda.)

Answer 3

You can execute the following instructions and command to solve the issue: (do not include inverted commas)

1. Open Anaconda Prompt
2. type: "create --name py3-TF2.0 python = 3"
3. press "y" to continue

After successful completion:

4. type "conda activate py3-TF2.0"
5. type "pip install matplotlib"
6. type "pip install tensorflow==2.1.0"
7. type "conda deactivate"
8. type "pip install ipykernel"
9. type "conda install nb_conda_kernels"

Now exit the Anaconda prompt and open the Anaconda Navigator application. Switch to "py3-TF2.0" from the base environment using the Environment tab. Install Jupyter in the specified environment. After successful installation, open Jupyter notebook and switch to "py3-TF2.0" kernel using Kernel Tab. You're good to go for using TensorFlow 2.

Make Sure you use Anaconda 2020.02 or lower version. As new version does not support TensorFlow 2.
