It looks like this install may not have completed correctly. If you open the Anaconda prompt and run "conda info" or "conda list", do you also see errors?
If all conda commands produce errors, then you will need to uninstall Anaconda and try again to reinstall it.
We have seen a few reports of failed installs like this, but we haven't been able to replicate the problem. It's possible that they could be caused by antivirus software preventing the install from working, or by other installations of Python on the same system interfering somehow, possibly by misconfiguration of the $PYTHONPATH or $PATH environment variables. We have also seen a few people who were able to solve the problem by uninstalling Anaconda, installing Miniconda, and then installing only the packages they need, or installing all the packages in Anaconda with the command "conda install anaconda".
If you do try to reinstall, please post any errors or warnings you see, and whether the reinstall is successful, since this may help us replicate the issue. Thanks!
