# TypeError with graphs.RandomGNP

I tried calling `gnp = graphs.RandomGNP(20, .1, algorithm = 'sage')`

and it gave me the following error

```
TypeError Traceback (most recent call last)

Not sure what went wrong here.. Appreciate any help! Thank you!

Did you install Sage with Conda? Or do you just have Anaconda in your PATH?

typical sage+python3 error ; already fixed in the latest beta
