Jupyter notebook is not opening anaconda 3 with python 3.7

I installed anaconda3 on my windows 10 with python 3.7, but when I open jupyter notebook from anaconda navigator or from start menu it is not opening, from anaconda prompt it is showing this message:

The install directory is "C:\ProgramData\Anaconda3"

Unfortunately the above step did not solve the problem for me as idna was already installed. I had to uninstall and reinstall idna following below commands.

  • pip uninstall idna
  • pip install idna

However,I got below prompts asking to install boto3.

  • Installing collected packages: idna
  • 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.
  • openimages 0.0.1 requires boto3, which is not installed.
  • cvdata 0.0.3 requires boto3, which is not installed. apache-beam 2.31.0 requires numpy<1.21.0,>=1.14.3, but you have numpy 1.22.4 which is incompatible.
  • apache-beam 2.31.0 requires
    typing-extensions<3.8.0,>=3.7.0, but you have typing-extensions 4.3.0 which is incompatible.

I did install boto3 using

  1. pip install boto3

Now I am not getting idna error anymore.

The easy way is to install idna by running the command below.

$pip install idna

That should solve the problem.
