Some problem while executing code

[tao840813]

Hi , i tried to executed some command codes from benchmark_scripts.

However, I met some problems:

1. There are some dimension problem when the program loading PyG dataset
   collate TypeError: cat_dim() takes 3 positional arguments but 4 were given
   So i modified the code in data.py from
   def cat_dim(self, key, value):
   to
   def cat_dim(self, key, value, *args, **kwargs):

2. atoms_to_points_normals
   Here comes some error like
   File exists: '/home/user/.cache/pykeops-1.5-cpython-38//build-pybind11_template-libKeOps_template_40f62f56de'

/home/user/.cache/pykeops-1.5-cpython-38:
formula: Sum_Reduction(Exp(Minus(Sqrt(Sum(Square((Var(0,3,0) - Var(1,3,1))))))),1)
aliases: Var(0,3,0); Var(1,3,1);
dtype : float32
...
make: *** 「KeOps_formula」。 。

      --------------------- MAKE DEBUG -----------------
      Command '['cmake', '--build', '.', '--target', 'KeOps_formula', '--', 'VERBOSE=1']' returned non-zero exit status 2.

Hi @tao840813

I am also trying to run their repo. I met the same problem as you have mentioned.

For problem 1, I think you have solved that problem. The following sentences are just for a supplementary purpose.

The reason we have this problem is because of the version issue of torch_geometric. You could see the difference between version 1.6.1 and latest version. Their __cat_dim__ function have different input requirements.

For problem 2, I did not meet the exact error. But I think it is the similar problem that relates to the version of KeOps. I have some errors when I use pip install pykeops but using pip install pykeops=1.4.1 solves the problem.

Best regards!

Hi @zshyang

For problem 2, it turns out that I installed wrong gcc version so that pykeops didn't install properly.
These problems are already solved right now.

Thank you for your response!
