Error windows 10 - miniconda3 64bit

[bjaraujo]

I get the following error trying to run:

from OCC.Display.SimpleGui import init_display
from OCC.BRepPrimAPI import BRepPrimAPI_MakeBox

display, start_display, add_menu, add_function_to_menu = init_display()
my_box = BRepPrimAPI_MakeBox(10., 20., 30.).Shape()

display.DisplayShape(my_box, update=True)
start_display()

@bjaraujo is is still failing ?

[bjaraujo]

I haven't checked recently. I will probably try again on the weekend.

[bjaraujo]

Should I install pythonocc-core==0.18.1 ?

[bjaraujo]

It gives during install:

conda install -c conda-forge -c dlr-sc -c pythonocc -c oce pythonocc-core==0.18.1 python=3.6

UnsatisfiableError: The following specifications were found to be in conflict:

• pythonocc-core==0.18.1 -> freetype==2.7
• scikit-image -> imageio[version='>=2.1.0'] -> pillow -> freetype[version='>=2.8,<2.9.0a0']
  Use "conda info " to see the dependencies for each package.

With python 3.6.3

[bjaraujo]

After removing freetype and installing pytonocc...

Still happens:

Fixed in current master.

[bjaraujo]

Good news, thanks. When will we have a new release?

[hypotenuse345]

Sorry to bother. I seem to encounter the same issue. Have you solved this problem yet?
My pythonocc version is latest(?) 0.18.2. Is this the problem of my computer itself, like missing some toolkits?
Here is the error report:

Same issue with conda install -c dlr-sc -c pythonocc pythonocc-core=7.4.0rc1 version

@Zebrafish007 I can't reproduce your issue. Can you please provide a list of all conda packages installed?
