我正在創建一個支持向量機。下面的模型讀取以“log”開頭的陣列作為 SVM 圖中的向量。陣列 log15-log21 將歸類為“c”，而行 log22-log36 將歸類為“d”。目標是以“log”行的格式為 svm 提供另一個向量，并讓 svm 將其標記為“c”或“d”。向量的內容背后是有含義的，但我不會用瑣碎的事情混淆你。

clf = svm.SVC()
clf.fit(X, y)
print(clf.predict([[0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0]]))
當我運行上面的代碼時，我收到此錯誤：
Traceback (most recent call last):
File "C:/Users/craig/Code/Python Programs/TensorFlowLabs/svm.py", line 34, in <module>
clf.fit(X, y)

我看到的在線指南沒有用逗號分隔向量，但向量陣列中的單個字符具有重要意義，因此如果有意義的話，我不希望 1 和 0 被“混淆”。
uj5u.com熱心網友回復：
您將 X 定義為一個陣列（您正在使用括號）。這就是您收到錯誤的原因。改變你定義 X 的方式，它應該可以作業：
X = lines
