导入模块导致属性错误

Question

在 python 脚本中，我尝试同时导入 Bokeh 和 Seaborn，但两次都收到错误消息。

这是使用 anaconda 完成的，另一个 python 脚本在另一个终端中运行。

import csv
import seaborn


x = []
y = []

with open('main.csv','r') as csvfile:
    plots = csv.reader(csvfile, delimiter=',')
    count = 1
    for row in plots:
        if count % 2 == 1:
            x.append(int(row[0]))
            y.append(int(row[1]))
        count += 1

seaborn.scatterplot(x, y)

导致以下错误消息：

AttributeError: module 'os' has no attribute 'sched_getaffinity'

Answer 1

调度程序函数，包括sched_getaffinity()，在 Windows 上不可用：

这些函数控制操作系统如何为进程分配 CPU 时间。 它们仅在某些 Unix 平台上可用。有关更多详细信息，请参阅 Unix 手册页。
