Cannot import `libroslz4.so` #2225

Closed aalbaali closed 2 years ago

Hello,

I have a LZ4 compressed rosbag. I have been working on the bag using Python 3 and was running smoothly until recently when I started getting this error: ImportError: libroslz4.so: cannot open shared object file: No such file or directory.

I looked around and found _roslz4.so stored under ~/.local/lib/python3.8/site-packages/roslz4/. However, Python 3 is not able to find it and it's giving me the error above.

Any idea as to what may be causing this issue and how to fix it?

Solved by installing roslz4 using

$ pip install roslz4 --extra-index-url https://rospypi.github.io/simple/
