- 将Protobuf软件包降级到3.20.x或更低。
- set protocol_buffers_python_implementation = python（但这将使用纯Python解析，并且会慢得多）。
这是我写的程序：
import cv2
import mediapipe as mp
import time
cap = cv2.VideoCapture(0)
while True:
success,img=cap.read()
cv2.imshow("Image",img)
cv2.waitKey(1)

_message.Message._CheckCalledFromGeneratedFile() TypeError: Descriptors cannot not be created directly. If this call came from a
_pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0. If you cannot immediately
regenerate your protos, some other possible workarounds are:
- Downgrade the protobuf package to 3.20.x or lower.
- Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
And this is the program I wrote:
import cv2
import mediapipe as mp
import time
cap = cv2.VideoCapture(0)
while True:
success,img=cap.read()
cv2.imshow("Image",img)
cv2.waitKey(1)

今天我面临同样的问题，同时我尝试在Google Colab中运行代码，并且效果很好。
I faced the same issue today, I tried to run the code in google Colab in the meantime and it worked well.
您可以更新Protobuf版本。
You can update the version of protobuf.
