Error in lesson 1 : “AttributeError: (‘This name is already taken’, ‘floatX’)”

I’m using a GPU on Google Cloud and had everything setup by using the script and steps provided by sebastian(many thanks to him) at How to set up env using Google Cloud?. I tried conda install pygpu in my home directory in my GCP instance but got an error

CondaError: No writable package cache directories found in
(u’/home/daksh/anaconda2/pkgs’, u’/home/daksh/.conda/pkgs’)

Any and all help is appreciated
