Arvados

When running my pipeline template, Arvados always sets up virtulenv and then install Python SDK. The problem is that "pip install" need proxy to download, but if I set the proxy, then I cannot connect to API service.

So, how could I configure proxy for pip without lose the connection of API service?

Additinally, I am curious about why Arvados needs to set up virtulenv and reinstall Python SDK. My template just includes a simple bwa command, and I've already install Python SDK in my docker image.

It would be a great help If someone could help me with these question, and I will pay great gratitude.
