I am trying to install tensorflow on a remote machine. I am only one of many users. The command I used (and was told to use) is:
pip install tensorflow --user
However, I got an error: "ResponseError('too many 503 error responses',)".
When I googled this error, it said it was more for HTTP requests overwhelming a server. That's not what I'm doing here, so why am I seeing this error, and how can I fix it?
[user#remote ~]$ pip install tensorflow --user
Collecting tensorflow

Seems like there are issues with files.pythonhosted.org https://status.python.org/
I think there are the same problem with pip site. I can not install anything with .

I m working behind a vpn and trying to use python requests, but I keep getting ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:1123). Once I turned down the vpn it worked as excepted. Is there any way to work around this issue?
Also one thing worth noting is that I tried to use postman while the vpn was on, and it worked fine.
Example
import requests
requests.get('https://www.google.com')

Then I tried to ignore SSL certificate verification.
ssl._create_default_https_context = ssl._create_unverified_context
by this line of code
but still getting the same error
How can I solve this problem?
Try to add acceptInsecureCerts = true capability. This will not work when your web site has strict transport security (HSTS) enabled.
this is my code:
import telebot
bot = telebot.TeleBot(Token)
#bot.message_handler(commands=["greet"])
def greeting(message):
bot.reply_to(message, "Hi")
bot.polling()
and this is the error I receive:

Connection is OK. Token is OK. It works manually when I browse https://api.telegram.org/botToken/getme and it works fine.
Other site for example google.com are OK too and works fine.
I would be glad to know what is the problem.
Actually because error I receive is too much a lot, stackoverflow does not allow me to post the question and wants me to add some more details, so I wrote this paragraph which is not related to the question and is just some words.
Do you have connected your telegram with a proxy? I can't solve your problem but you can follow this post: Problem connecting telegram bot through Python
I have a code that runs 24/7 (while true on the main.py file) with multiprocessing (12 workers) that accesses gcloud on a regular basis (listing buckets, downloading etc.)
I dont think its a regular ssl error because I get ssl error only one time throughout a day long run and every subprocess access their own gs client.
I dont really understand why the error happens or how to fix it since the same traceback gives me two types of errors.
Also worked everything until i increased the amount of my workers.
The way i create my client:
def get_gs_bucket():
storage_client = storage.Client.from_service_account_json(JSON_CREDENTIALS_PATH)
gs_bucket_name = BUCKET_NAME
return storage_client.get_bucket(gs_bucket_name)
the function that's mentioned in the error:
def list_gs_dir(prefix=''):
sleep_random_prevent_gs_over_api_usage()
return gs_bucket.list_blobs(delimiter='/', prefix=prefix)._get_next_page_response()['prefixes']

I have built a crawler script that download webpages using urllib3 and python3. I ran the crawler in a Google Cloud Virtual Machine instance and tried it with many different urls. I found a url that i couldn't download on the VM instance but succeeded to download on my personal Linux.
The code that i've tried on my computer and worked:
>>> import urllib3
>>> pool = urllib3.PoolManager()
>>> response = pool.request('GET', 'http://www.azlyrics.com/lyrics/drake/dowhatyoudo.html')
>>> response.status
200
I have tried the exact same code on the VM instance using ssh and this exception occurred:

I have checked the VM dashboard and I didn't find any firewall or other restrictions that I may have mistakenly defined.
What could it possibly be?
