Website crawl behind a company proxy in python

I try to built a website crawl in behind behind a company proxy.
So far I am running the following code:
import requests
url = 'https://www.bundesliga.com/de/bundesliga/spieltag/2022-2023/19/fc-augsburg-vs-bayer-04-leverkusen/lineup'
def get_url_content(url):
return requests.get(url).text
get_url_content(url)
And i am running into the following errors:

705 method,
706 url,
707 timeout=timeout_obj,

710 chunked=chunked,
It seems like the command is blocked by the company proxy, how can I handle the error? Also for other Urls it is the same error.
There is the option to change the proxy with:
requests.get(url, proxies = { "https" : "https://1.1.0.1:80"})
but I have no idea which proxy I have to use.

So it seems not to be able to open the stopwords file. I have checked the data folders and it is present.
when it can't find it it then tries to find the spacy file 'en_core_web_sm'
I cannot find this in the folders although spacy is there.
I then get a time out as it can't find the file.
I have tried uninstalling and reinstalling spacy and texthero and updating both.
I have tired installing en_core_web_sm and the other versions
e.g. using code:
!pip install https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.0/en_core_web_sm-2.2.0.tar.gz
and
!python -m spacy download en_core_web_sm
I have tried reinstalling/updating nltk
I have run in Jupyter notebook and in Python and CMD (as admin). all with the same error.
I've tried both python commands and pip to do the above installs etc.
I really don't know what else to try
any ideas?
thanks

Run distributed TensorFlow, UnavailableError: Endpoint read fail

I am new to TensorFlow and do not have much experience. I am now trying the distributed TensorFlow.
Following the official guide, I first create two servers. I run the following code in two seperate terminals
import sys
import tensorflow as tf
task_number = int(sys.argv[1])
cluster = tf.train.ClusterSpec({"local": ["localhost:2222", "localhost:2223"]})
server = tf.train.Server(cluster, job_name="local", task_index=task_number)
print("Starting server #{}".format(task_number))
server.start()
server.join()
The server has been set up successfully
2018-01-25 20:05:37.651802: I tensorflow/core/distributed_runtime/rpc/grpc_channel.cc:215] Initialize GrpcChannelCache for job local -> {0 -> localhost:2222, 1 -> localhost:2223}

Then I run the following program
import tensorflow as tf
x = tf.constant(2)
with tf.device("/job:local/task:1"):
y2 = x - 66
with tf.device("/job:local/task:0"):
y1 = x + 300
y = y1 + y2
with tf.Session("grpc://localhost:2223") as sess:
result = sess.run(y)
print(result)
Then it gives me the following error message

I googled it and some suggest that it might be the problems with proxy, so I have disabled the proxy but nothing changed.
Does anyone have any ideas what the problems might be? Many thanks in advance.
Never mind, problems solved. It is the setting about the proxy. We need to unset proxy on both servers and clients to make the program work.

Error while reading h5 file in pandas in read mode

I read the file this way

Urllib raising invalid argument URLError in Python 3, urllib.request.urlopen

New to Python, but I'm trying to...retrieve data from a site:
import urllib.request
response = urllib.request.urlopen("http://www.python.org")
This is the same code I've seen from the Python 3.1 docs. And a lot of sites.
However, I get:
Message File Name Line Position

I have no idea what's causing this. Anyone know?
Maybe try turning off the firewall? Since you are on Windows, that might be the problem.
