将pandas DateTimeIndex转换为(可迭代的)Unix时间的惯用方法是什么？这可能不是要走的路:

[time.mktime(t.timetuple()) for t in my_data_frame.index.to_pydatetime()]

我有一个包含的数据框

user_id    date       browser  conversion  test  sex  age  country
   1    2015-12-03       IE        1         0    M   32.0   US

到目前为止,这是我的整个代码!

data["country"].fillna("missing")
data["age"].fillna(-10000, inplace=True)
data["ads_channel"].fillna("missing")
data["sex"].fillna("missing")
data['date'] = pd.to_datetime(data.date)

columns = data.columns.tolist()
columns = [c for c in columns if c not in ["test"]]
from sklearn import tree
clf = tree.DecisionTreeClassifier(max_depth=2, min_samples_leaf = (len(data)/100) )
clf = clf.fit(data[columns],data["test"])

我收到此错误:
