Good day. Im having an issue with LZ4 in python 3.6 and 3.8. Even though that lz4 is installed, and the wrappers too, Im getting an error that doesnt allow me open the bag. Any ideas? all this in Ubuntu 18.04.6 LTS with ros melodic This is not happening in python2

ubuntu@ubuntu:~$ python3 -m pip list | grep lz
lz4                           3.1.10
lz4-cffi                      1.0.5
python-lzf                    0.2.4
roslz4                        1.14.13

You can not easily run python3 from a ros melodic node. The easiest path forward is for you to upgrade to noetic if you need to use python3.
