我遇到了同樣的問題，因爲它是這裏所描述大廈多重圖從熊貓數據幀 - 「類型錯誤：unhashable類型：‘字典’」
Networkx Multigraph from_pandas_dataframe
雖然我在convert_matrix.py取代線211， 「類型錯誤：不可用類型：'字典'」仍然存在。我想用下面的數據框（鏈接）來構建多圖：
1_id f v v_id_1 v_id_2
0 3483 50 38000 739 2232
1 3482 50 38000 717 2196
2 3482 50 22000 717 2196
3 3480 50 22000 1058 2250
data = {'1_id':[3483, 3482, 3482, 3480], 'v_id_1':[739, 717, 717, 1058], 'v_id_2':[2232,2196, 2196, 2250], 'v':[38000, 38000, 22000, 22000], 'f':[50, 50, 50, 50]}
links = pd.DataFrame(data)
G=nx.from_pandas_dataframe(links, 'v_id_1', 'v_id_2', edge_attr=['v','f'], create_using=nx.MultiGraph())
嘗試創建多重圖，我發現了錯誤：
TypeError Traceback (most recent call last)

嗨，你能提供完整的錯誤信息和[mcve]嗎？謝謝。 – Joel
