Hi Tiago, I am on Ubuntu 19.04, and I upgraded to the graph-tool 2.32 (edited sources.list, update and apt-get install). Now when I try to import graph tool using "import graph_tool.all as gt", I get the following error: import graph_tool.all as gt File "/usr/lib/python3/dist-packages/graph_tool/__init__.py", line 106, in <module> dl_import("from . import libgraph_tool_core as libcore") File "/usr/lib/python3/dist-packages/graph_tool/dl_import.py", line 58, in dl_import exec(import_expr, local_dict, global_dict) File "<string>", line 1, in <module> ImportError: libboost_python3-py36.so.1.65.1: cannot open shared object file: No such file or directory Could you kindly suggest a solution? Thanks and regards, Snehal Shekatkar
