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.

what is the output of the command "conda env list"? – Lakshmi - Intel
# conda environments: # base * D:\Anaconda tensorflow1 D:\Anaconda\envs\tensorflow1 this is the output of "conda env list" – Yasin Demirkaya

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.
