TypeError: ‘weights_only‘ is an invalid keyword argument for Unpickler()解决

使用torch_geometric.datasets的Planetoid，提前下载了数据放在raw目录，第一次执行没问题，第二次执行就报TypeError: 'weights_only' is an invalid keyword argument for Unpickler()。

定位了下发现是torch_geometric.datasets的Dataset有问题，其_process函数中的torch.load(f, weights_only=False)用法有问题，删掉weights_only=False即可，更改后代码如下：

  def _process(self):
        f = osp.join(self.processed_dir, 'pre_transform.pt')
        if osp.exists(f) and torch.load(f) != _repr(
                self.pre_transform):
            warnings.warn(
                "The `pre_transform` argument differs from the one used in "
                "the pre-processed version of this dataset. If you want to "
                "make use of another pre-processing technique, pass "
                "`force_reload=True` explicitly to reload the dataset.")

        f = osp.join(self.processed_dir, 'pre_filter.pt')
        if osp.exists(f) and torch.load(f) != _repr(
                self.pre_filter):
            warnings.warn(
                "The `pre_filter` argument differs from the one used in "
                "the pre-processed version of this dataset. If you want to "
                "make use of another pre-fitering technique, pass "
                "`force_reload=True` explicitly to reload the dataset.")
