AttributeError: 'NoneType' object has no attribute 'pos' about vedo HOT 8 CLOSED

Hi, I might have introduced a bug in the dev version ....
Is the error also showing up in the released version?

pip uninstall vedo
pip install vedo -U

from vedo.

it did not work. I got this error now:

ImportError: cannot import name 'Volume' from 'vedo' (unknown location)

from vedo.

I think there must be something else going wrong there.. you should post a minimal script with the complete error message, e.g

from vedo import Volume
vol= Volume()
print(vol)

Does it work from command line eg.

vedo --run numpy2volume0

from vedo.

sure, here is my complete code:

import numpy as np
from vedo import Volume
from vedo.applications import Slicer3DPlotter
import matplotlib.pyplot as plt

f = open('data.bin', 'rb') 
content = f.read() 
f.close() 

data = np.frombuffer(content, np.float32)
print(data)

data_3d = data.reshape((200,200,700),order='F')

vol = Volume(data_3d)

plot3D = Slicer3DPlotter(vol)

plot3D.show()

I have numpy 1.26.4, vedo 2024.5.1 and matplotlib 3.8.4

from vedo.

You did not show the exact error message. Can you reproduce this?

import numpy as np
from vedo import Volume
from vedo.applications import Slicer3DPlotter

data = np.zeros([70, 80, 90], dtype=np.uint8)
data[ 0:30,  0:30,  0:30] = 1
data[30:50, 30:60, 30:70] = 2
data[50:70, 60:80, 70:90] = 3

vol = Volume(data)

plot3D = Slicer3DPlotter(vol)
plot3D.show()

from vedo.

I reproduced your code in spyder with vedo 2024.5.1 and I get the following error:

AttributeError: 'NoneType' object has no attribute 'pos'

If I use:

pip uninstall vedo
pip install vedo -U

and run the same code with spyder I get the following error: ImportError: cannot import name 'Volume' from 'vedo' (unknown location)

from vedo.

The second error message points to a problem in your anaconda installation.
I just run the above script in a spyder version 5 console and it runs normally..

from vedo.

Let me know if need further help on this.
I'm closing the issue for the moment.

from vedo.
