New submission from serge g <sergeg.2kgr...@gmail.com>: I am not sure if it is python's issue (correct me if this is wrong place for report). But sometimes (probably every 3-4 attempt) when I run script, interpreter just stucks for some time (0.5-3 minutes) and then actually runs the script normally.
To figure out what happens I increased verbosity (python -vv) and actually python hangs on import on this line: ... # trying /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/hazmat/primitives/kdf/scrypt.abi3.so # trying /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/hazmat/primitives/kdf/scrypt.so # trying /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/hazmat/primitives/kdf/scrypt.py # /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/hazmat/primitives/kdf/__pycache__/scrypt.cpython-37.pyc matches /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/hazmat/primitives/kdf/scrypt.py # code object from '/home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/hazmat/primitives/kdf/__pycache__/scrypt.cpython-37.(pyc' (here >>>>>) import 'cryptography.hazmat.primitives.kdf.scrypt' # <_frozen_importlib_external.SourceFileLoader object at 0x7f5c6e3c73c8> import 'cryptography.hazmat.backends.openssl.backend' # <_frozen_importlib_external.SourceFileLoader object at 0x7f5c6c129c88> import 'cryptography.hazmat.backends.openssl' # <_frozen_importlib_external.SourceFileLoader object at 0x7f5c6d30d240> # trying /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/x509/UnsupportedExtension.cpython-37m-x86_64-linux-gnu.so # trying /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/x509/UnsupportedExtension.abi3.so # trying /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/x509/UnsupportedExtension.so # trying /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/x509/UnsupportedExtension.py # trying /home/2kg/spider/venv/lib/python3.7/site-packages/cryptography/x509/UnsupportedExtension.pyc ... I had version 3.5 installed before and didn't notice such issue. Other scripts from my project suffer from this symptom as well.
