Hi. I'm running Mint-19.0 Tara, based largely on Ubuntu debs. I can confirm the bug. 1st time, it takes 3-4 seconds. It's a fresh install, duly updated & upgraded. I tried running it from a terminal, and got this:
------------
dec@RoseViolet:~$ invesalius3
/usr/share/invesalius/invesalius/data/transformations.py:1899: UserWarning: failed to import module _transformations
warnings.warn("failed to import module %s" % name)
session mode: 0
Looking at that transformations.py, the offending routine is below:
-----------
def _import_module(name, package=None, warn=True, prefix='_py_', ignore='_'):
"""Try import all public attributes from module into global namespace.
Existing attributes with name clashes are renamed with prefix.
Attributes starting with underscore are ignored by default.
Return True on successful import.
"""
import warnings
from importlib import import_module
try:
if not package:
module = import_module(name)
else:
module = import_module('.' + name, package=package)
except ImportError:
if warn:
1899 ===>>> warnings.warn("failed to import module %s" % name) <<<=== 1899
else:
for attr in dir(module):
if ignore and attr.startswith(ignore): continue
if prefix:
if attr in globals(): globals()[prefix + attr] = globals()[attr] elif warn: warnings.warn("no Python implementation of " + attr) globals()[attr] = getattr(module, attr)
return True
-------------
I'm no python expert, but I gather it's a dependency issue. I also tried the debian .deb, but got exactly the same fault(segfault after 3-4 seconds). It's a pity, it's a well recommended piece of kit. As I was trying packages, I did a 'purge' on each one followed by an 'autoremove'. I have a few VMs (Mint, Vista, W10), but because there's a fault noted in W64 (app.py, line 146) I'm not tempted to try a windows version.
