When you have a Macbook, and I trying to install this code: conda env create -f [https://quantra.quantinsti.com/downloads/machinelearning/environment.yml](https://quantra.quantinsti.com/downloads/machinelearning/environment.yml), in the Terminal under anaconda/jupyter, and this give you an error like this: Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘ProxyError(‘Cannot connect to proxy.’, OSError(‘Tunnel connection failed: 403 Forbidden’))’: /downloads/machinelearning/environment.yml

Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘ProxyError(‘Cannot connect to proxy.’, OSError(‘Tunnel connection failed: 403 Forbidden’))’: /downloads/machinelearning/environment.yml

Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘ProxyError(‘Cannot connect to proxy.’, OSError(‘Tunnel connection failed: 403 Forbidden’))’: /downloads/machinelearning/environment.yml

ProxyError: Conda cannot proceed due to an error in your proxy configuration.  
Check for typos and other configuration errors in any ‘.netrc’ file in your home directory,  
any environment variables ending in ‘\_PROXY’, and any other system-wide proxy  
configuration settings.

please can help me to resolved this issue?

Hi,

I think it might just be an error with accessing that URL that you are using. Maybe it has some authentication that isn’t being realised by the terminal.

If you download the yml file instead, you can use the [import environment](https://www.anaconda.com/docs/tools/anaconda-navigator/tutorials/manage-environments#importing-an-environment) tool in Navigator and it installed fine for me.

Hope that helps,  
Jack
