ModuleNotFoundError: 'CuGraphSAGEConv' requires 'pylibcugraphops>=23.02'

😵 Describe the installation problem

I am trying to run this code block:

import torch.nn.functional as F
from torch_geometric.nn import CuGraphSAGEConv

class CuGraphSAGE(torch.nn.Module):
    def __init__(self, in_channels, hidden_channels, out_channels, num_layers):
        super().__init__()

        self.convs = torch.nn.ModuleList()
        self.convs.append(CuGraphSAGEConv(in_channels, hidden_channels))
        for _ in range(num_layers - 1):
            conv = CuGraphSAGEConv(hidden_channels, hidden_channels)
            self.convs.append(conv)

        self.lin = torch.nn.Linear(hidden_channels, out_channels)

    def forward(self, x, edge, size):
        edge_csc = CuGraphSAGEConv.to_csc(edge, (size[0], size[0]))
        for conv in self.convs:
            x = conv(x, edge_csc)[: size[1]]
            x = F.relu(x)
            x = F.dropout(x, p=0.5)

        return self.lin(x)

model = CuGraphSAGE(128, 64, 349, 3).to(torch.float32).to("cuda")
optimizer = torch.optim.Adam(model.parameters(), lr=0.01)

but I get this:

Which version of pylibcugraphops did you have installed?
