cannot install python api

[rsj007]

I am installing python api on my jetson tx2 by running "python3 get_python_api.py". However it seems that I can't connect to the download page.

The output is below: `vidia@nvidia:/usr/local/zed$ python3 get_python_api.py -> Downloading to '/usr/local/zed' JETPACK 45 Detected platform: jetsons Python 3.6 ZED SDK 3.4 -> Checking if https://download.stereolabs.com/zedsdk/3.4/jetsons/jp45/py36 exists and is available Traceback (most recent call last): File "/usr/lib/python3.6/urllib/request.py", line 1325, in do_open encode_chunked=req.has_header('Transfer-encoding')) File "/usr/lib/python3.6/http/client.py", line 1281, in request self._send_request(method, url, body, headers, encode_chunked) File "/usr/lib/python3.6/http/client.py", line 1327, in _send_request self.endheaders(body, encode_chunked=encode_chunked) File "/usr/lib/python3.6/http/client.py", line 1276, in endheaders self._send_output(message_body, encode_chunked=encode_chunked) File "/usr/lib/python3.6/http/client.py", line 1042, in _send_output self.send(msg) File "/usr/lib/python3.6/http/client.py", line 980, in send self.connect() File "/usr/lib/python3.6/http/client.py", line 1442, in connect server_hostname=server_hostname) File "/usr/lib/python3.6/ssl.py", line 407, in wrap_socket _context=self, _session=session) File "/usr/lib/python3.6/ssl.py", line 817, in init self.do_handshake() File "/usr/lib/python3.6/ssl.py", line 1077, in do_handshake self._sslobj.do_handshake() File "/usr/lib/python3.6/ssl.py", line 689, in do_handshake self._sslobj.do_handshake() OSError: [Errno 0] Error

During handling of the above exception, another exception occurred:

What should I do to solve the problem?

You should check that the time and date are correctly set on your jetson, this can trigger certificate issues. You can also check if you can access the URL in a browser or using wget.

A workaround is to install the package manually, eg

wget https://download.stereolabs.com/zedsdk/3.4/jetsons/jp45/py36 -O pyzed-3.4-cp36-cp36m-linux_aarch64.whl

python -m pip install ./pyzed-3.4-cp36-cp36m-linux_aarch64.whl

Same error here, on Windows 10! I'm getting this error:

urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:997)>

on line 175, urllib.request.urlretrieve(whl_file_URL, whl_file). Any suggestion? From my browser the access is denied.
