【问题描述】:
我正在尝试使用此处的代码:https://github.com/pystruct/pystruct/blob/master/examples/multi_label.py
我有形状为(2591, 256) 的X_train 和形状为(2591, 175) 的y_train。当我运行这个时:
tree = chow_liu_tree(y_train)
tree_model = MultiLabelClf(edges=tree, inference_method="max-product")
tree_ssvm = OneSlackSSVM(tree_model, inference_cache=50, C=.1, tol=0.01)
print("fitting tree model...")
tree_ssvm.fit(X_train, y_train)
我知道了:
Traceback (most recent call last):
File "classifiers.py", line 173, in <module>
tree_ssvm.fit(X_train, y_train)
File "/usr/local/lib/python2.7/dist-packages/pystruct/learners/one_slack_ssvm.py", line 448, in fit

File "utils.pyx", line 21, in utils.__pyx_fused_cpdef (src/utils.c:4341)
TypeError: No matching signature found
当我直接从链接运行代码时,它可以工作(使用他们的数据集)。有人知道应该是什么问题吗?
