I followed this website ( https://www.pyimagesearch.com/2015/03/30/accessing-the-raspberry-pi-camera-with-opencv-and-python/ ) to set my picamera, but I have a problem with the picamera module. I did install the picamera module, and this picture is from pip freeze.
You can see I have picamera 1.13 already, but when I try test_image.py, it says "No module named 'picamera'".
I have uninstalled and installed many times, but the error still exist. How do I fix this?
test_image.py
# import the necessary packages
from picamera.array import PiRGBArray
from picamera import PiCamera
import time
import cv2
# initialize the camera and grab a reference to the raw camera capture
camera = PiCamera()
rawCapture = PiRGBArray(camera)
# allow the camera to warmup
time.sleep(0.1)
# grab an image from the camera
camera.capture(rawCapture, format="bgr")
image = rawCapture.array
# display the image on screen and wait for a keypress
cv2.imshow("Image", image)
cv2.waitKey(0)
for python3 you have to just try this below commands.keep in mind that you need to open terminal in home directory.
sudo -H apt install python3-picamera
sudo -H pip3 install --upgrade picamera[array]
let me know if it works!
When you run the command pip3 install picamera , it will show that the requirement is already satisfied followed by a path , provided if you have already installed picamera. Now copy that path and include it in your program as follows:
import sys
sys.path.append('paste the copied path here')
from picamera.array import PiRGBArray
from picamera import PiCamera
我遇到了同样的问题,直到我注意到我没有在 PiCamera 中大写 c
Try the following commands from: https://www.raspberrypi.org/documentation/linux/software/python.md
I'm assuming the path for the picamera module is messed up for some reason, so try purging it and reinstalling it.
Purge using:
sudo apt purge python3-picamera
First make sure everything is up to date:
sudo apt update
Then:
sudo apt install python3-picamera
使用以下步骤安装 picamera 模块
1.On Windows, execute: set READTHEDOCS=True
1'.On Unix based systems, execute: export READTHEDOCS=True
2.Now execute: pip install picamera
Pi camera may not work on windows try following commands, it will resolve issue
execute:
set READTHEDOCS=True
Now execute:
pip install picamera
When I had a file named picamera.py, I had the same problem so I renamed it and since more problem. I hope it's the same for you, otherwise it's above my skills.
