TimeoutError when installing with pip

Autonomous Machines Jetson & Embedded Systems Jetson Xavier NX
1

Hello.
I am trying to install the python libraries needed for TensorRT python samples (on Jetson Xavier).
“python3 -m pip install -r requirements.txt”
I constantly get the following error:
"'ReadTimeoutError(“HTTPSConnectionPool(host=‘pypi.org’, port=443): Read timed out”

In addition tried with pip3(didn’t help)
Also increased the default timeout (using --default-timeout=500)and still got these errors
I don’t have problems to access the python website via the regular browser. I also checked network definitions and in the proxy section the method is “none”

No others ideas left. Maybe you could help me

Best regards

Someone solved this issue to disable IPV6 from here:

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1

I got the exact same TimeoutError when installing with pip, but the suggested solution didn’t solve the problem for me. It just replaced the error I get with a different one:

raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://pypi.org/simple/python3-opencv/

Any ideas?

Thanks a lot!

Hello @nmiron7

Maybe you can upgrade your pip:
$ python3 -m pip install --upgrade pip

Have you checked proxy settings? When I had this problem one of the answers I found in stackoverflow relates to this

Hello @marinak and @mehmetdeniz and thank you for your replies
Unfortunately neither solutions worked for me.

@mehmetdeniz you suggested upgrading my pip, but I cannot upgrade anything using pip (not even pip itself), since I get the same TimeoutError

@marinak I tried the solution with the proxies, using this code:
python3 -m pip --proxy http://user:pass@server:port install python3-opencv

From which I have gotten the following error:

Any insights?

Thanks again!

Unfortunately I don’t know. In my case, I just saw that proxy is not used in my web settings. So I eliminated this issue. However, I don’t know how to solve the issue it when proxy is used.

Hey @marinak and @mehmetdeniz

I solved the problem.
I have been using my home network, and couldn’t use pip at all.
I tried to switch to a mobile hotspot and somehow everything now magically works!
I have no idea why though…

Thanks for trying to help! I appreciate it!

So I guess it has something to do with your network but we didn’t figured out what can it be. In my case it was the ipv6 . Anyway , it is good you have a workaround
