+### Windows compilation
+On Windows you may have this error when compiling:
+```
+error: member "torch::jit::detail::ModulePolicy::all_slots" may not be initialized
+error: member "torch::jit::detail::ParameterPolicy::all_slots" may not be initialized
+error: member "torch::jit::detail::BufferPolicy::all_slots" may not be initialized
+error: member "torch::jit::detail::AttributePolicy::all_slots" may not be initialized
+```
+This requires you to edit some of your pytorch header files, use [this script](https://github.com/rusty1s/pytorch_scatter/blob/master/script/torch.sh) as a guide.

 ### CUDA kernel failed : no kernel image is available for execution on the device
 
 This can happen when trying to run the code on a different GPU than the one used to compile the `torch-points-kernels` library. Uninstall `torch-points-kernels`, clear cache, and reinstall after setting the `TORCH_CUDA_ARCH_LIST` environment variable. For example, for compiling with a Tesla T4 (Turing 7.5) and running the code on a Tesla V100 (Volta 7.0) use:
