我在 macOS 上运行 Python 3.7.0，并且使用 pip 安装了 scikit-learn 版本 0.20.1。我也安装了 numpy 和 scipy。

当我尝试以下代码时：

from sklearn import svm

我收到以下错误：

Traceback (most recent call last):

  File "/usr/local/lib/python3.7/site-packages/sklearn/svm/__init__.py", line 13, in <module>

    print "%s version %s" % (os.path.basename(sys.argv[0]), __version__)
                    ^
SyntaxError: invalid syntax

如果我只是导入 sklearn（不指定 svm），我不会收到任何错误。

请问我可以得到这个错误的帮助吗？
