Hi! Could you give more information about your environment? Like what are the versions for TorchDrug and PyTorch?

wzy-Sarah commented 1 year ago

After encountering this problem, I uninstall the torchdrug. And now I cannot install the torchdrug, the error is: error: legacy-install-failure

× Encountered error while trying to install package. ╰─> torch-scatter

But I already install torch-scatter and my environment is : windows python=3.7 pytorch=1.7.1+cu110 torch_geometric = 2.0.4 torch_cluster = 1.5.9 torch_scatter = 2.0.6 torch_sparse = 0.6.9 torch_spline_conv = 1.2.1 deepchem = 2.6.1 rdkit
