Detectron MetadaCatalog 和 DatasetCatalog 导入失败

Question

我正在尝试在 Google Colab 上包含 Detectron2.data。 我为 colab 和我的驱动器建立了连接。之后：

!pip install pyyaml
!pip install detectron2 -f https://dl.fbaipublicfiles.com/detectron2/wheels/cu101/torch1.7/index.html

它没有任何错误。

我一直在尝试这个；

import numpy as np
import os, json, cv2, random
from google.colab.patches import cv2_imshow


import detectron2
from detectron2.data import MetadataCatalog, DatasetCatalog
from detectron2.utils.visualizer import Visualizer
from detectron2 import model_zoo

但是输出是这样的： enter image description here

我该如何解决？

Answer 1

我是这样修复的：

!pip install pyyaml==5.1
import torch, torchvision
print(torch.__version__, torch.cuda.is_available())
!gcc --version


import torch
assert torch.__version__.startswith("1.8")   
!pip install detectron2 -f https://dl.fbaipublicfiles.com/detectron2/wheels/cu101/torch1.8/index.html
# exit(0)  # After installation, you need to "restart runtime" in Colab. This line can also restart runtime
