Solution is to install wget first. It doesn't automatically provides wget as in the requirements file pip3 install wget also upgrade pip if not done

We were requiring the operating system wget (via os.execute('cd {path}; wget {url}')), #47 should fix this by using the python wget package which is now included in the requirements file. Thanks for the report!

should be resolved, let me know if you experience any further issues!

Even after doing "pip3 install -r requirements.txt" I was still experiencing this error on my Mac machine. brew install wget finally resolved the issue
