用pyecharts的Page类作图，为什么使用page.render("page_name")修改文件名称会报错，默认名称没有问题

Question

def drawing():
page = Page()
'''
中间是一些数据
'''
page.add(line)#通过add将多张line
page.render("page_name")#通过render这个函数修改名字

###########################################
报错的地方，如果用page.render(）默认生成是可以的
Traceback (most recent call last):
File "E:/Python/pyproject/pyechats/Drawing_ppm.py", line 187, in
drawing()
File "E:/Python/pyproject/pyechats/Drawing_ppm.py", line 176, in drawing
page.render("page_name")
File "C:\Python27\lib\site-packages\pyecharts\custom\page.py", line 89, in render
"Rendering Page instance as image is not supported!"
NotImplementedError: Rendering Page instance as image is not supported!

请帮忙看下是什么原因。

Answer 1

page.render(u'./name.html')

Answer 2

还有个问题我的目录中有中文--E:\Python\测试一览表,page.render()需要怎么转编码？
