Install into a new environment instead of the conda base environment. Recent Anaconda and Miniconda installers have Python 3.7 in the base environment, but you're trying to install something that requires Python 3.6.

As others have said, it's recommended to create a new, clean environment and conda install into that.

This can be done with the following:

# Create new environment
conda create --name <name> python=3.6
# Activate new environment
conda activate <name>
# Install packages into new environment
conda install -c conda-forge ecmwf-api-client

It's a good idea to keep various environments for different projects. You can then use conda deactivate/conda activate <name> and install any packages into the correct environment. This also allows you to easily swap between different versions of python, or individual software packages.

  1. Simply go to Anaconda navigator.
  2. Go to Environments, Select Installed (packages, etc.) and then click the version of Python. Downgrade it to a lower version. In your case Python 3.6

Don't know if you managed to fix this but in case some others got stuck here is the solution that I found:

Just simply used pip3 inside of conda env. It has installed opencv for python3.6 without any issue:

pip3 install opencv-python
