Detectron MetadaCatalog和DatasetCatalog导入失败

Question

我正在尝试包含 connection 2. Google .上的数据，我为colab和我的驱动器建立了连接。在那之后：

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

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

但是输出如下：在这里输入图像描述

我怎么才能解决呢？

Answer 1

我就这样修正了：

!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
