我正在使用Python通过一个名为wot的工具使用jupyter notebook来可视化一个图形。它利用了Gephi,一个基于java的图形工具。我尝试运行函数返回坐标输出文件,如下所示:
run_gephi(input_graph_file, output_coord_file, n_steps):
layout = 'fa'
import psutil
memory = int(0.5 * psutil.virtual_memory()[0] * 1e-9)
classpath = os.path.dirname(
pkg_resources.resource_filename('wot', 'commands/resources/graph_layout/GraphLayout.class')) + ':' + \
pkg_resources.resource_filename('wot', 'commands/resources/graph_layout/gephi-toolkit-0.9.2-all.jar')
subprocess.check_call(['java', '-Djava.awt.headless=true', '-Xmx{memory}g'.format(memory=memory), '-cp', classpath, \
'GraphLayout', input_graph_file, output_coord_file, layout, str(n_steps), str(os.cpu_count())])
然后它在我的jupyter笔记本中返回以下错误:
CalledProcessError Traceback (most recent call last)

在终端中发现以下消息
Error: Could not find or load main class GraphLayout
“我能找到”GraphLayout.java文件“和”gephi-toolkit-0.9.2-全部.jar“文件在路径中,所以我真的不知道为什么不能加载。 你有什么建议吗?你知道吗
GraphLayout类不包含在Gephi中,而是由GraphLayout.java文件. 你知道吗
