I use:
Debian 10, 64bit
Electrum 4.1.0 with all dependencies installed
I run Electrum without installing it and receive two warning messages. They are:
/usr/lib/python3/dist-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.24.1) or chardet (4.0.0) doesn't match a supported version!
RequestsDependencyWarning)
/home/username/electrum/packages/bitstring.py:36: DeprecationWarning: invalid escape sequence \
"""
I appreciate your help in solving the above.
