问题描述
我正在尝试使用 Visual Studio 2017 社区中的 NetworkX Python 包读取 GraphML 文件，使用以下代码：
import networkx as nx
import glob
import re
data = {}
graphs = {}
for graphml in glob.glob("*.graphml"):
m = re.match(r'^ant_mersch_col([0-9]+)_day([0-9]+)_attribute.graphml$',graphml).groups()
if m[0] not in data.keys():
data[m[0]] = []
graphs[m[0]] = {}
data[m[0]].append(m[1])
graphs[m[0]][m[1]] = nx.read_graphml(graphml)
为简洁起见，我省略了大部分节点和边，但这是我正在尝试阅读的缩写 GraphML 文件：
<?xml version='1.0' encoding='utf-8'?>
<graphml xmlns="http://graphml.graphdrawing.org/xmlns" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd"><key id="d16" for="edge" attr.name="weight" attr.type="long"/>

顺便说一下，这个文件是来自 Network Repository 的 ant 数据；对于那些好奇的人，可以找到完整的文件here。
我在我的 IDE 中得到了一个相当模糊的异常 'long'，它显然是一个基于堆栈跟踪的 KeyError：

'long'
奇怪的是，当我在 Spyder 中运行几乎相同的代码时，不会发生这种情况。
有谁知道为什么这会在 Visual Studio 2017 中发生（但在 Spyder 中不会）以及我该如何解决？
