1运行run_videopy时出现如下问题
cmd: Union[List[str], str], ^ SyntaxError: invalid syntax原因是EasyProcess版本与python版本不对应解决办法可见之前这篇博客SyntaxError: invalid syntax。
2解决完上述问题后输入命令 python run_video.py RL 2 0结果又出现了新的错误 出错的原因在chromedriver上解决办法可见之前这篇博客Message: ‘chromedriver‘ executable may have wrong permissions.
3之后再运行如果出现这样的错误
Message: unknown error: net::ERR_CONNECTION_REFUSED(Session info: chromexxx.xxx.xxx.xxx)解决办法一是看run_video.py文件中的url设置情况根据项目中其他文件中的代码设置一般设置url http://localhost:8333/ myindex_ abr_algo .html。 若没有上述问题二是要注意RL方法中使用的模型是否在对应的路径中。 可以单独运行python rl_server_no_training.py 0进行实验结果发现以下报错 检查存储模型的目录…/rl_server/results/发现少了pretrain_linear_reward.ckpt.index文件立即去github上重新下载一个。
然后再运行 python rl_server_no_training.py 0结果如下解决。
4是按照项目Real-world experiments中的说明运行后发现无法得出结果。
项目内说明 To run real-world experiments, first setup a server (setup.py automatically installs an apache server and put needed files in /var/www/html). Then, copy over the trained model to rl_server/results and modify the NN_MODEL filed of rl_server/rl_server_no_training.py. Next, modify the url field in real_exp/run_video.py to the server url. Finally, in real_exp/ run python run_exp.py The results will be saved to real_exp/results folder. More details can be found in real_exp/README.md. 5 本地测试pensieve代码中rl_server_no_training.py的交互功能
当我在postman中设置好Body 并输入post的内容‘{“RebufferTime”:1,“lastquality”:1,“lastChunkFinishTime”:1,“lastChunkStartTime”:1,“lastChunkSize”:1,“buffer”:1}’。不过post后postman出现错误
Error: socket hang up服务器出现报错 File E:\anaconda\envs\pensieve\lib\json\decoder.py, line 382, in raw_decoderaise ValueError(No JSON object could be decoded)
ValueError: No JSON object could be decodedPostman 错误 “Error: socket hang up” 这个错误通常是因为服务器在处理请求时遇到了问题并关闭了连接可能是由于代码中的异常引起的。
服务器端错误 “ValueError: No JSON object could be decoded” 这个错误是因为服务器尝试解析POST请求中的JSON数据时失败了。POST请求中包含JSON数据但在服务器端尝试解析它时出现问题。第二个问题似乎是导致第一个问题的原因。 遇到这种情况首先检查Postman中的请求头确保 Content-Type 设置为 “application/json”以指示服务器接收JSON数据。此外还要注意postman中传输数据的格式我传输内容设置为’{“RebufferTime”:1,“lastquality”:1,“lastChunkFinishTime”:1,“lastChunkStartTime”:1,“lastChunkSize”:1,“buffer”:1}这是导致错误的原因。应该直接以字典传书就可以{“RebufferTime”:1,“lastquality”:1,“lastChunkFinishTime”:1,“lastChunkStartTime”:1,“lastChunkSize”:1,“buffer”:1}。 Send之后 问题解决。 当然以上post内容设置适用于postman软件如果是在python中发送post内容则要注意了
import requests
url http://x.x.x.x:x
# data {x:1,xx:1,xxx:1,xxxx:1,xxxxx:1,xxxxxx:1} 错误
data {x:1,xx:1,xxx:1,xxxx:1,xxxxx:1,xxxxxx:1}
response requests.post(url, datadata)
if response.status_code 200:print(Request successful)print(Response content:, response.text)
else:print(Request failed with status code:, response.status_code)
此时data不能为字典需是字符串否则服务器也会出现错误
raise ValueError(No JSON object could be decoded)
ValueError: No JSON object could be decoded发送端代码会出现错误
requests.exceptions.ConnectionError: (Connection aborted., BadStatusLine(,))正确的反馈
6 向pensieve代码中rl_server_no_training.py发送post
利用python向后台运行中的rl_server_no_training.py发送post出现报错
Traceback (most recent call last):File test.py, line 4, in moduleresponse requests.post(url, datadata)File /home/xxx/anaconda3/envs/pensieve/lib/python2.7/site-packages/requests/api.py, line 117, in postreturn request(post, url, datadata, jsonjson, **kwargs)File /home/xxx/anaconda3/envs/pensieve/lib/python2.7/site-packages/requests/api.py, line 61, in requestreturn session.request(methodmethod, urlurl, **kwargs)File /home/xxx/anaconda3/envs/pensieve/lib/python2.7/site-packages/requests/sessions.py, line 529, in requestresp self.send(prep, **send_kwargs)File /home/xxx/anaconda3/envs/pensieve/lib/python2.7/site-packages/requests/sessions.py, line 645, in sendr adapter.send(request, **kwargs)File /home/xxx/anaconda3/envs/pensieve/lib/python2.7/site-packages/requests/adapters.py, line 501, in sendraise ConnectionError(err, requestrequest)
requests.exceptions.ConnectionError: (Connection aborted., BadStatusLine(,))
这个问题好办我们检查rl_server_no_training.py那边的情况
Traceback (most recent call last):File rl_server_no_training.py, line 298, in modulemain()File rl_server_no_training.py, line 293, in mainrun()File rl_server_no_training.py, line 279, in runhttpd server_class(server_address, handler_class)File /home/xxx/lib/python2.7/SocketServer.py, line 417, in __init__self.server_bind()File /home/xxx/envs/pensieve/lib/python2.7/BaseHTTPServer.py, line 108, in server_bindSocketServer.TCPServer.server_bind(self)File /home/xxx/anaconda3/envs/pensieve/lib/python2.7/SocketServer.py, line 431, in server_bindself.socket.bind(self.server_address)File /home/xxx/anaconda3/envs/pensieve/lib/python2.7/socket.py, line 228, in methreturn getattr(self._sock,name)(*args)
socket.error: [Errno 98] Address already in use
地址被占用rl_server_no_training.py压根没运行成功。 这里利用sudo lsof -i :端口号显示使用系统上端口的进程及其相关网络连接的列表然后利用kill -9 进程号关闭即可。
7 在代码中增加log记录
为了以后方便在服务器代码运行中检测到错误与问题决定在服务器代码中加入log记录。 以rl_server_no_training.py为例首先
import logging
logging.basicConfig(filenamenohup.out, levellogging.DEBUG)
logger logging.getLogger(server)
def make_request_handler(input_dict):class Request_Handler(BaseHTTPRequestHandler):def __init__(self, *args, **kwargs):self.input_dict input_dictself.sess input_dict[sess]self.log_file input_dict[log_file]self.actor input_dict[actor]self.critic input_dict[critic]self.saver input_dict[saver]self.s_batch input_dict[s_batch]self.a_batch input_dict[a_batch]self.r_batch input_dict[r_batch]BaseHTTPRequestHandler.__init__(self, *args, **kwargs)def do_POST(self):logger.info(Received a POST request)# 省略logger.debug(Received POST data: %s, post_data)我开始在run中添加log错误做法
def make_request_handler(input_dict):class Request_Handler(BaseHTTPRequestHandler):def __init__(self, *args, **kwargs):self.input_dict input_dictself.sess input_dict[sess]self.log_file input_dict[log_file]self.actor input_dict[actor]self.critic input_dict[critic]self.saver input_dict[saver]self.s_batch input_dict[s_batch]self.a_batch input_dict[a_batch]self.r_batch input_dict[r_batch]BaseHTTPRequestHandler.__init__(self, *args, **kwargs)def do_POST(self):logger.info(Received a POST request)def run(server_classHTTPServer, port8334, log_file_pathLOG_FILE):np.random.seed(RANDOM_SEED)logging.basicConfig(filenamenohup.out, levellogging.DEBUG)logger logging.getLogger(server)# 省略handler_class make_request_handler(input_dictinput_dict)
但是报错
File rl_server_no_training.py, line 75, in do_POSTlogger.info(Received a POST request)
NameError: global name logger is not defined要使记录器变量在两个函数中都可访问您可以在更高的范围内定义它如在模块级别。 请确保将此代码放在脚本的开头放在使用记录器变量的任何函数或类之前。 修改之后成功显示记录
8 浏览器向服务器发送POST请求中因CORS跨域资源共享问题导致的net::ERR_FAILED错误 如上图所示使用浏览器向服务器发送POST请求时出现net::ERR_FAILED错误经排查是因CORS跨域资源共享问题导致。 检查js代码发现httpRequest.setRequestHeader(Content-type,application/json)而CORS中的简单请求Simple Request要求头只能是text/plain、multipart/form-data、application/x-www-form-urlencoded。 所以我们需要将Content-type设置为application/x-www-form-urlencoded。 原来的代码许多也需要修改下面是一个示例 Content-type为application/json时的版本
const urlhttp://xxx.xxx.xxx.xxx:8333/;var dict{RebufferTime:rebuffertime,lastquality:lastQuality,lastChunkFinishTime:lastChunkFinishTime,lastChunkStartTime:lastChunkStartTime,lastChunkSize:lastChunkSize};console.log(dict)var encodedData encodeFormData(dict);console.log(encodedData)var httpRequest new XMLHttpRequest();httpRequest.open(POST,url,true);httpRequest.setRequestHeader(Content-type,application/x-www-form-urlencoded);// httpRequest.setRequestHeader(Content-type,application/json);httpRequest.send(JSON.stringify(encodedData));Content-type为application/x-www-form-urlencoded时的版本
function encodeFormData(data) {const formData new URLSearchParams();for (const key in data) {formData.append(key, data[key]);}return formData.toString();}const urlhttp://xxx.xxx.xxx.xxx:8333/;var dict{RebufferTime:rebuffertime,lastquality:lastQuality,lastChunkFinishTime:lastChunkFinishTime,lastChunkStartTime:lastChunkStartTime,lastChunkSize:lastChunkSize};console.log(dict)var encodedData encodeFormData(dict);console.log(encodedData)var httpRequest new XMLHttpRequest();httpRequest.open(POST,url,true);httpRequest.setRequestHeader(Content-type,application/x-www-form-urlencoded);// httpRequest.setRequestHeader(Content-type,application/json);//httpRequest.send(JSON.stringify(encodedData));httpRequest.send(encodedData.toString());服务器接收端的代码也需要修改如下是可以正常运行的版本
content_length int(self.headers[Content-Length])
postdataself.rfile.read(content_length)
parsed_data parse_qs(postdata)
# 将列表中的字符串转换为浮点数或整数
for key, value_list in parsed_data.items():if key RebufferTime or key lastChunkFinishTime or key lastChunkStartTime:parsed_data[key] float(value_list[0])else:parsed_data[key] int(value_list[0])因为接收到的postdata是字符串例如“RebufferTime0.014999866485595703lastquality1lastChunkFinishTime1696524371.103lastChunkStartTime1696524371.088lastChunkSize66752”
9 parsed_data parse_qs(postdata)可能遇到的错误SyntaxError
parsed_data parse_qs(postdata)是使用urlparse解析数据字符串使之转换成字典。 运行parsed_data parse_qs(postdata)时也有可能出现报错SyntaxError: Non-ASCII character \xe7 in file D:/xxx Ŀdebug/test3.py on line 3, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details 这个错误表明Python脚本文件中包含了非ASCII字符但是没有指定文件的编码方式。在Python 2.7中默认的源文件编码是ASCII如果文件中包含非ASCII字符就需要在文件的开头声明文件编码。 要解决这个问题可以在脚本文件的开头添加编码声明以指定文件的编码方式。例如如果文件使用UTF-8编码可以这样声明
# -*- coding: utf-8 -*-
from urlparse import urlparse, parse_qs
# 示例数据字符串
data_string RebufferTime0.014999866485595703lastquality1lastChunkFinishTime1696524371.103lastChunkStartTime1696524371.088lastChunkSize66752
# 使用urlparse解析数据字符串
parsed_data parse_qs(data_string)
# 输出转换后的字典
print(parsed_data)
10 开启rl_server_no_training.py服务器时的socket.error: [Errno 10049]错误
今天在pycharm运行rl_server_no_training.py欲启动服务器时却出现如下错误
Traceback (most recent call last):File xxx/rl_server_no_training.py, line 333, in modulemain()File xxx/rl_server_no_training.py, line 326, in mainrun(log_file_pathLOG_FILE _RL_ trace_file)File xxx/rl_server_no_training.py, line 314, in runhttpd server_class(server_address, handler_class)File xx\anaconda\envs\pensieve\lib\SocketServer.py, line 420, in __init__self.server_bind()File xx\anaconda\envs\pensieve\lib\BaseHTTPServer.py, line 108, in server_bindSocketServer.TCPServer.server_bind(self)File xx\anaconda\envs\pensieve\lib\SocketServer.py, line 434, in server_bindself.socket.bind(self.server_address)File xx\anaconda\envs\pensieve\lib\socket.py, line 228, in methreturn getattr(self._sock,name)(*args)
socket.error: [Errno 10049] Process finished with exit code 1
解决办法可见socket.error: [Errno 10049]错误解决。
