问题 I'm learning flask and im up to the blueprint section. First of all, i have the header.html which is included by base.html, and the route for index is below: @app.route('/') def index(): return render_template("index.html", is_auth=session[is_authenticated], username=session[username]) header.html: {% if is_auth %} Welcome {{ username }}</font>, {% else %} <a href="{{ url_for('users.register') }}"> Register / Login</a></li> {% endif %} base.html is simple: {% block header %} {% include

你和 BAT 的数据分析师差在哪儿?

说起近几年热门高薪的工作,数据分析师绝对算得上头牌。 一方面薪资高,打开拉勾招聘 App 就会发现,数据分析师的岗位薪资都是20K起。 另一方面,数据分析师目前依旧还是企业的强需求,大量的企业都很难招到合格的数据分析人员。(Burning Glass Technologies的数据显示,未来 10 年,数据分析师的工作预计还将增长 14.3%。) 那么问题来了—— 你的薪资水平,达到均值了么? 你觉得你是心仪公司的“香饽饽”吗? 坦诚地讲,目前虽然有很多人在从事数据分析的岗位,但最多只能叫“提数机器”。他们的典型特征就是:半路出家、不懂业务、不懂技术。 15 年,你会用 Excel,会查 SQL 数据库,那你不难找到一份数据相关的好工作。 后来,你得会做 BI 可视化,会用 SPSS 做数据挖掘,能做漂亮的报表,还得了解点 Python …… 现在,MySQL 、 Python 、 BI 这些都是数据分析的基础技能,除此之外,你还要懂统计、数据清洗、特征工程、建模、算法…… 而且互联网红利期已经过去,凭“感觉”,靠“经验”去做决策的风险越来越大,只有通过高质量的数据分析,才能更加直观高效准确。 这也从业务需求上,倒逼数据从业者有更高的数据分析能力。对于那些底层数据分析师,高薪前景都与他们无关,还面临随时被踢出局的风险。 到底该如何有效提升数据分析能力,制胜职场? 这个双十一

How to do object detection on a video stream coming from a websocket url

问题 I am getting a stream from a source which I made so that it can be accessed at a particular websocket URL (Not sure if this ideal and would appreciate any other architectures as well). I need to now do object detection on this video stream, and thought of the architecture that I will connect to the websocket URL through a client websocket library like websocket in a server which is made through flask or fastapi, and then again stream the object detected video to multiple clients through

Why does scrapy crawler only work once in flask app?

巧了我就是萌 提交于 2021-01-07 02:36:54
问题 I am currently working on a Flask app. The app takes a url from the user and then crawls that website and returns the links found in that website.

Two Flask apps on different paths with Kubernetes Ingress resource (nginx)

半世苍凉 提交于 2021-01-07 01:32:53
问题 My goal is the following: I have two Flask apps in two separate Docker containers and I want to access them via different paths on the same IP address, like this: 127.0.0.1/app1, 127.0.0.1/app2 (but with a real IP address). I want to do this with Kubernetes. I have a Kubernetes cluster running (Azure Kubernetes Service), with a Deployment and Service for each of the two Docker containers. The pod for each app is running fine. I also installed an ingress controller (Nginx) in my cluster and
