Error: "Double requirement given" when using requirements.txt for assignment1

[shagunsodhani]

Following requirements are mentioned twice in reuirements.txt that comes with the zip file for assignemnt 1.

• jupyter (1.0.0 both times)
• pillow (3.1.0 and 3.0.0)

This gives the error "Double requirement given" when running pip install -r requirements.txt

I see the same problem. Removing the Pillow==3.0.0 line and one jupyter==1.0.0 line worked.

If someone knows a way to get pip to do a "dry run" (find out what it would do, without actually e.g. downgrading matplotlib from 1.5.1 to 1.5.0), let me know....

Try pip3 install packagename --no-build-isolation
