[GRASS-user] grass.script.array

[Margherita Di Leo]

Hi List,

I guess the module 'array' in grass.script library doesn't work properly in
grass 6.5 but does in 7 .

    import grass.script.array as garray

    ....

    slope = garray.array()
    area = garray.array()

    slope.read('r_slope')
    area.read('r_area')

    fig = plt.figure(figsize=(8, 8))
    ax = fig.add_subplot(1, 1, 1)
    ax.set_yscale('log')
    ax.set_xscale('log')

    plt.plot(area,slope,'ro')

In grass 6.5 I get:

Sorry, <bytes> is not a valid parameter

In grass 7 it works. Did anyone experienced it?
Thanks,
