undefined symbol error

[KaiyueSun98]

Hi, I have a undefined symbol error when importing the GLIPDemo in Colab demo. I use torch==1.9.0, torchvision==0.10.0 and CUDA 12.0. Is there any way to solve the issue?

Thanks ImportError Traceback (most recent call last) Cell In[1], line 10 8 pylab.rcParams['figure.figsize'] = 20, 12 9 from maskrcnn_benchmark.config import cfg ---> 10 from maskrcnn_benchmark.engine.predictor_glip import GLIPDemo 12 def load(url): 13 """ 14 Given an url of an image, downloads the image and 15 returns a PIL image 16 """
