当我尝试在virtualenv(pip install MySQL-python)中安装MySQL-python时,我收到以下错误(截断到最后几行)

我无法找到bokeh-server能够处理的会话数.

我想在我的网络应用程序中包含一些图表,并想知道单个散景服务器如何在任何给定时间处理约100个用户的流量.每个用户的页面可能在页面上有多达10个散景图.我会redis用作后端

我的堆栈如下(所有在单核VPS,1G RAM上):

• nginx (网络服务器)
• uwsgi (应用服务器)
• flask (网络框架)
• redis (内存数据持久性)

bokeh-server配置选项如何影响--multi-user我的用例？我无法理解散景的范围session.

我在 Flask Web 应用程序中建立 websocket 时遇到问题。

在客户端，我每秒向服务器发出一个“ping”websocket 事件。在浏览器控制台中，我每秒看到以下错误

POST https://example.com/socket.io/?EIO=3&transport=polling&t=LOkVYzQ&sid=88b5202cf38f40879ddfc6ce36322233 400 (BAD REQUEST)

GET https://example.com/socket.io/?EIO=3&transport=polling&t=LOkVZLN&sid=5a355bbccb6f4f05bd46379066876955 400 (BAD REQUEST)

WebSocket connection to 'wss://example.com/socket.io/?EIO=3&transport=websocket&sid=5a355bbccb6f4f05bd46379066876955' failed: WebSocket is closed before the connection is established.

我有以下 nginx.conf

server {
    listen 80;
    server_name example.com www.example.com;
    return 301 https://$server_name$request_uri;
}

upstream app_server {

    # for UNIX domain socket setups
    server unix:/pathtowebapp/gunicorn.sock fail_timeout=0;

}

server {

    listen 443 ssl;

    server_name example.com www.example.com;

    keepalive_timeout 5;

    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

我有一个处理csv文件的程序.CSV的内容如下

lines = [
 [id_A, val1, val2, ..., valn],
 [id_A, val1, val2, ..., valn],
 [id_B, val1, val2, ..., valn],
 [id_B, val1, val2, ..., valn],
 [id_B, val1, val2, ..., valn],
 [id_B, val1, val2, ..., valn],
 [id_C, val1, val2, ..., valn],
 [id_C, val1, val2, ..., valn],
 ]

我正在建立一个看起来像的字典

my_dict = {
 'id_A': ['many', 'values'],
 'id_B': ['many', ''more', 'values']
 'id_C': ['some', 'other', 'values']}

我目前的实现看起来像

for line in lines:
    log_id = line[0]
        if log_id not in my_dict.keys():
            datablock = lines[1:]
            my_dict[log_id] = datablock
        else: …
