'float' object cannot be interpreted as an integer

Hi,

When trying to process Sentinel-2 data, I am getting error:

During handling of the above exception, another exception occurred:

I am using Python3.6

Does it help if you change the line:

wave_hyper = linspace(wave_range[0],wave_range[1],((wave_range[1]-wave_range[0])/wave_step)+2)

to:

wave_hyper = linspace(wave_range[0],wave_range[1],ceil(((wave_range[1]-wave_range[0])/wave_step)+2))

You'll also need to import ceil from numpy.

It seems this occurs in the most recent Python/numpy distribution. This commit should help: https://github.com/acolite/acolite/commit/650331e634940fe7c9a0d8c6ff0d72855d5ae593

Same issue here, despite the updates in that commit. I now have:

Hi Quinten,

The 3rd parameter in linespace should be casted as the int type. It seems that the ceil did not work in my macOS because it still generates the float64 number.

I tried this command as follows and it worked.

wave_hyper = linspace(wave_range[0],wave_range[1],int(ceil((wave_range[1]-wave_range[0])/wave_step)+2))

Thanks Zhigang,

Will update shortly, it seems ceil still returns a float!

I have updated the code to pass integers to linspace - my apologies for the long wait!
