hi, did you install the specified versions of pytorch and pytroch-lightning? I think ptl changes the this module in later versions...

thanks for your reply!
I I followed the Prerequisites and installed pytorch==1.7.1 and pytorch-lightning==1.5.4, with torch-geometric==1.7.1

Hi, try pytorch-lightning==1.3.1, as specified. I will try to make things work with later versions, but for some reasons I had worse results with later ptl version (which should not be the case...)

I have tried pytorch-lightning==1.3.1 and it works!
BUT there is a new problem that p = np.random.randint(low=self.p_min, high=self.p_max) in synthetic_graphs/data.py line:100, where low=0.4, high=0.6 settings are errors for this line.
I don't understand this a bit, and thanks for your replies!

Same, I solved by replacing the line with np.random.uniform(low=self.p_min, high=self.p_max)
