TypeError: Invalid type conversion to ArrayImg [32x32x32] requested.

[carshadi]

Hi,

It appears I am not able to use the imglyb.to_numpy(rai) method

import imglyb
import scyjava

scyjava.start_jvm()

Views = imglyb.util.Views

ArrayImgs = scyjava.jimport("net.imglib2.img.array.ArrayImgs")

img = ArrayImgs.floats(32,32,32)
print(img.dimensionsAsLongArray())

arr = imglyb.to_numpy(img)

yields

[32, 32, 32]

I used a fresh conda environment on WIndows 10

conda create -n imglyb-test -c conda-forge python=3.9 imglyb
conda activate imglyb-test

Downgrading jpype to 1.4.0 and 1.3.0 did not help

Update: installing from source fixed the issue
