TypeError: new(): invalid data type 'str', when converting graph from networkX

[euerka]

Hi,
May I seek for your advice regarding to following issue:

TypeError Traceback (most recent call last)
in
10 print(data)
11 G = to_networkx(data, node_attrs=['x'], edge_attrs=['edge_attr'])
---> 12 data = from_networkx(G)
13 print(data)

/workspace/conda-env/lib/python3.8/site-packages/torch_geometric/utils/convert.py in from_networkx(G, group_node_attrs, group_edge_attrs)
190 else:
191 try:
--> 192 data[key] = torch.tensor(value)
193 except ValueError:
194 pass

TypeError: new(): invalid data type 'str'

when the below code is run:

`import torch
from torch_geometric.data import Data
from torch_geometric.utils import erdos_renyi_graph, to_networkx, from_networkx

edge_index = erdos_renyi_graph(50, edge_prob=0.2)
x = torch.randn(50, 64)
edge_attr = torch.randn(edge_index.size(1), 32)
data = Data(edge_index=edge_index, x=x, edge_attr=edge_attr)

print(data)
G = to_networkx(data, node_attrs=['x'], edge_attrs=['edge_attr'])
data = from_networkx(G)
print(data)`

There is no such kind of issue when the code run in another OS system.

Thanks!
