A reportable application error has occurred. Conda has prepared the above report.
If submitted, this report will be used by core maintainers to improve

Would you like conda to send this report to the core maintainers?

After few hours looking up online I couldn't find a solution.

Your issue and your question can be very different.

Your issue has something to do with SSL connection: SSLError(MaxRetryError( . Try to check if your inte.net connection is working well, try to access https://repo.anaconda.com to see if it works.

Your question of "how to create an environment in conda" has been answered many times here, and it is documented on the official website. BUT make sure to pay attention to these confusing commands below, you can either run

• conda create -n test , OR
• conda env create -f environment.yml where environment.yml is a configuration file

Also note that conda env create -n test will not work any more.

See this for the latest docs.
