Make sure to change the path to libsecp256k1! It is presented as a list in the load_library () method
. I am writing a brute under Ubuntu, then for detecting libsecp256k1 I left the only way:


library_paths = ['/usr/lib/x86_64-linux-gnu/libsecp256k1.so.0']



PS: To find libsecp256k1.so.0 on your system, use the find utility:



find /usr/ -iname "libsecp256k1.so.0"
