Missing become password in ansible playbook -

-

i trying create playbook deploy simple scenario: login server , clone/update open github repo. access parameters written in ~/.ssh/config

here files:

  1. hosts

    [staging]

    staging

  2. deploy.yml

    - hosts: staging   tasks:   - name: update code   git: repo=https://github.com/travis-ci-examples/php.git dest=hello_ansible

    when trying run ansible-playbook -s deploy.yml -i hosts, outputs error this:

gathering facts *************************************************************** fatal: [staging] => missing become password

task: [update code] *********************************************************** fatal: no hosts matched or hosts have failed -- aborting

i have tried add sudo: false , become: false, not seem have effect. assume operation should not request sudo password trying work files in ssh user's home directory.

i sorry if question bit lame, not have experience ansible.

it asking sudo password because using -s option. seems not want use sudo task try running command without -s.

ansible-playbook deploy.yml -i hosts

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
