Hi
I am getting this error while installing with VCStudio or Jupyter.

I am using Python 3.7.1
Used command: pip3 install vedo

Collecting vedo

The conflict is caused by:
vedo 2021.0.2 depends on vtk
vedo 2020.4.2 depends on vtk
vedo 2020.4.1 depends on vtk<9.0.0
vedo 2020.4.0 depends on vtk
vedo 2020.3.4 depends on vtk
vedo 2020.3.3 depends on vtk
vedo 2020.3.2 depends on vtk

To fix this you could try to:

loosen the range of package versions you've specified
remove package versions to allow pip attempt to solve the dependency conflict

Note: you may need to restart the kernel to use updated packages.

Hi @hilaal thanks for reporting, that's very strange!
Have you tried to uninstall first?
pip3 uninstall vedo
(repeat multiple times untill all versions disappear)

Currently we have in the requirements.txt this one line:

vtk==8.1.2,>=7

which seems ok by looking at the explanations from your link, i dont quite understand the error message..
any ideas?

Hi Thank you ver much for your immediate response. I just followed your instructions. Other than that I don’t really understand anything :-). I had not installed Vedo previously. Despite of that I tried to uninstall it from my system.

Try first this:
pip3 uninstall vtk
pip3 install vedo -U

If this (probably) doesn't work then try:

git clone https://github.com/marcomusy/vedo.git
cd vedo
rm requirements.txt
pip3 install .

Hi Marco Thanks. I have installed. The issue was with pip3. I upgraded the pip3 and then installed. Thank you for the support.

Fine.. What I understood was...

pip install vedo works alright as follows but pip3 install vedo does not work...

hilaalalam@Hilaals-MacBook-Pro-4 ~ % pip install vedo
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: vedo in ./Library/Python/3.8/lib/python/site-packages (2021.0.2)
Requirement already satisfied: numpy in ./Library/Python/3.8/lib/python/site-packages (from vedo) (1.20.2)
Requirement already satisfied: vtk in ./Library/Python/3.8/lib/python/site-packages (from vedo) (9.0.1)

pip3 install vedo does not work...

thanks again for reporting this strange behavior ... indeed it seems the problem is with pip3 and vtk as
pip3 install vtk already gives an error on my mac, but not on my ubuntu system

Yes. So any other way out? Because I am using Python3 for several projects and hence I cannot come out of that.

I can post a question to the VTK experts forum, but it may take a while to get an answer.

Hi
I have moved to Ubuntu 20 on Mac. I have installed VEDO successfully.
Python3 is at /usr/bin/python3
Vedo us at /usr/local/bin/vedo

Now I ran the following sample code

from vedo import Cone
c = Cone()
c.show(axes=1)

In terminal Python3 it works fine. SUCCESS...!

But in Visual Studio Code, it throws the following error message

Traceback (most recent call last):
File "vedo.py", line 1, in
from vedo import Cone
File "/home/hilaal/Desktop/Simulation/vedo.py", line 1, in
from vedo import Cone
ImportError: cannot import name 'Cone' from partially initialized module 'vedo' (most likely due to a circular import) (/home/hilaal/Desktop/Simulation/vedo.py)

No! You cannot name a user script with the package name! Call it differently (not vedo.py)
