python基础问题

[小A软件测试]

在使用django框架开发web的过程中，我需要使用django-simple-captcha来使用验证码功能，python3.5，django1.11.6，captcha0.4.6，但是在按照官方的帮助写代码的时候，却出现了这个问题，由于不知道其中的原理，所以纠结了很久，百度也查不到解决方案，只好来求助、错误代码：

根据我调试的结果，view.py中是可以接受到验证码的，但是在传到模版去显示的是时候除了问题，传不过去。
view.py
from django.shortcuts import render,render_to_response
from .form import RegisterForm


def some_view(request):
if request.POST:
form = RegisterForm(request.POST)

# Validate the form: the captcha field will automatically
# check the input
if form.is_valid():
human = True
else:
form = RegisterForm()

return render_to_response('register.html', locals()) # 如果为真，则进入指定页面
register.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
{{ form.captcha }}
</body>
</html>

我也遇到过，升级下captcha就可以了
