When I open Jupyter Notebook there is a Kernel Error appears

Question

I've been trying to work on a Python project about object detection with TensorFlow. Everything was okay until I run my Jupyter Notebook in my environment "tensorflow1". When Jupyter Notebook opens there is a red Kernel Error appearing at the top righthand side of my window. When I click it gives a message like

Traceback (most recent call last):

ImportError: DLL load failed: The specified procedure could not be found.

I tried to change the Kernel but I had only one Kernel called "Python3". I tried to remove it and created a new Kernel called "Python tensorflow1". I tried to run the codes with that Kernel and it still gives me that red error.

It also says Failed to start the Kernel.

Answer 1

Please activate the environment tensorflow1 and install ipykernel in that environment uing below commands:

conda activate tensorflow1
conda install ipykernel
ipython kernel install --name tensorflow1 --user

Then try to use access jupyter notebook using the below command:

jupyter notebook

If the above steps doesn't work please follow the below steps to create a new conda environment and access jupyter notebook from that environment:

conda create -n env_tf -c intel python=3.6

Once the conda environment is created successfully, you can list the environment using the below command:

conda env list

It should be listing:

D:\Anaconda\envs\env_tf

Activate the environment using the below command:

conda activate env_tf

Install ipykernel in the activated environment:

conda install ipykernel

ipython kernel install --name env_tf --user 

Access jupyter notebook using below command:

jupyter notebook

Hope this helps.
