I downloaded z3 source codes from the master branch and tried to build it, which resulted in the following error:
c:\Program Files\z3>python --version
Python 3.3.2
c:\Program Files\z3>python scripts\mk_make.py
Traceback (most recent call last):

from mk_util import *
File "c:\Program Files\z3\scripts\mk_util.py", line 81
print "dos2unix '%s'" % fname

SyntaxError: invalid syntax
Am I doing something wrong?
The master branch only works with Python 2.7.x.
The unstable (working-in-progress) branch should work with Python 3.x.
Here are instructions to compile the working-in-progress branch.

I do not know what the problem is. If I start container and build it manually it works.
If I create it manually then I am getting following error:
Conan: Version found ERROR: Can't write version file in /.conan/version.txt
I added the following environment variable to my jenkinsfile. Then it simply works!. I was trying to define env variables in docker container that was my fail
environment {
CONAN_USER_HOME = "${env.WORKSPACE}/"
CONAN_NON_INTERACTIVE = 1
}
Running the example /examples/kuka_iiwa_arm/kuka_simulation gives me the following error:

Information about my system:

drake was built from source using bazel 0.29.0
If I run
bazel-bin/tools/drake_visualizer &
./bazel-bin/manipulation/util/geometry_inspector ./manipulation/models/iiwa_description/sdf/iiwa14_no_collision.sdf
The Kuka arm is shown in the visualizer and I can use the sliders to control the configuration of the arm.
Edit: My problem is that when I run /examples/kuka_iiwa_arm/kuka_simulation, no frames are displayed in the visualizer.
This should be fixed once we update the version of Director shipped with Drake.
We're already in the process of doing so via our Python 3 update: https://github.com/RobotLocomotion/drake/issues/12046
Thanks for reporting this!
I'm trying to run DSSP through Biopython, a couple of months ago the code worked, however, I now get this erroe. Any help would be much appreciated.
>>>from Bio.PDB.PDBParser import PDBParser
>>>from Bio.PDB.DSSP import DSSP
>>>p=PDBParser(PERMISSIVE=1)
>>>st= p.get_structure('1bzq','1bzqK.pdb')
>>>model=st[0]
>>>dssp= DSSP(model,'1bzqK.pdb',dssp='dssp')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/rennes/akhila/.local/lib/python2.7/site-packages/Bio/PDB/DSSP.py", line 355, in __init__
except FileNotFoundError:
NameError: global name 'FileNotFoundError' is not defined
I have checked the path of dssp also by
user#home:~/Documents/FR_distances$ mkdssp
mkdssp 2.2.1 options:
-h [ --help ] Display help message
-i [ --input ] arg Input file
-o [ --output ] arg Output file, use 'stdout' to output to screen
-v [ --verbose ] Verbose output
--version Print version
-d [ --debug ] arg Debug level (for even more verbose output)
I have also referred to this and changed the dssp path, but still it gives me the same error.
From source code:
Note that the recent DSSP executable from the DSSP-2 package was
renamed from dssp to mkdssp. If using a recent DSSP release, you
may need to provide the name of your DSSP executable:
>>> dssp = DSSP(model, '1mot.pdb', dssp='mkdssp')
Try replacing dssp= DSSP(model,'1bzqK.pdb',dssp='dssp') by:
dssp = DSSP(model, '1bzqK.pdb', dssp='mkdssp')
this is driving me crazy, I already tried a lot of things,e.g. changing locale, but still getting this after workspace init and then doing catkin_make on subdir.

Thank you very much!
It looks like an unicode problem. In very brief summary, you have passed something that is being interpreted as a string of bytes to something that needs to decode it into Unicode characters, but the default codec (ascii) is failing.
More on this here.
there's a lot of solutions to this one. the one I suggest is doing this :
yassin#pc:/usr/local/lib/python2.7/site-packages# cat sitecustomize.py
# encoding=utf8
import sys
reload(sys)
sys.setdefaultencoding('utf8')
and to check if that works, you need to do the following :
yassin#pc:~/home# python
Python 2.7.6 (default, Dec 6 2013, 14:49:02)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> reload(sys)
<module 'sys' (built-in)>
>>> sys.getdefaultencoding()
'utf8'
>>>
Hope it helps ! Cheers.
Set the system default locale to en_IN.utf8 should solve the problem.
For example, if you use bash, you can add below lines into your ~/.bashrc:
LANG=en_IN.utf8
export LANG
The catkin toolkit use system default locale to load message or service files.
I'm trying to start learning OpenCV but I can`t even create the framework.
I'm using this command like the instructions said
python opencv/ios/build_framework.py ios
But I'm getting the following error:
