Question

我在sklean doc sklearn_doc上关注此示例，我可以执行该示例，但如果我从以下地址更改：

fetch_lfw_people(min_faces_per_person=70, resize=0.4)

到

fetch_lfw_people(min_faces_per_person=200, resize=1.0)

除了这些参数之外我没有改变任何东西，是另一个int的int和另一个float的浮点数，我看不到问题

我收到以下错误：

ImportError: The Python Imaging Library (PIL) is required to load data from jpeg files

更改参数时fetch_lfw_people错误（Python）
