cv2 and mediapipe aren't installed in Blender (checked through blender python console), despite mediapipe appearing in pip list -u in console.

Environment: Windows 10

Error message follows

Please try this code. on the script screen

import subprocess
import sys
import os

# path to python.exe
python_exe = os.path.join(sys.prefix, 'bin', 'python.exe')

# upgrade pip
subprocess.call([python_exe, "-m", "ensurepip"])
subprocess.call([python_exe, "-m", "pip", "install", "--upgrade", "pip"])

# install required packages
subprocess.call([python_exe, "-m", "pip", "install", "opencv-python"])

and click run like this :

Created a new script, c+p the code you posted, and ran. After it finished, I tried importing video via mediapipe and got the same error.

[carlosedubarreto]

can you run again the code I provided and place here the result that shows on the console? (it must show the instalation log)

[Eydec]

Nothing in the python console,

bpy.ops.text.run_script() In the Info console

[carlosedubarreto]

Oh sorry, I mean this console

then something like this will show

Then you run the code again e post here the result, please

looks like it installed the opencv on your default windows python instalation.

Do this. on windows explorer, go to this address c:\users\appdata\roaming\python\python37\site-packages

copy the folder "cv2"

and paste it here c:\program files\blender foundation\blender 2.91\2.91\python\lib\site-packages
