New question #692820 on Yade: https://answers.launchpad.net/yade/+question/692820
Sorry to bother you sir, My YADE version is yade-2019.01a and I am working on Ubuntu 18.04. I am trying to run biaxialSmooth.py from FEM-DEM examples. Then get the error I get is this: PicklingError: Can't pickle <type 'function'>: attribute lookup __builtin__.function failed. I have read the same issue in https://answers.launchpad.net/yade/+question/686704 , and his solution is '' It is all about paths. Where and how you creat yadeimport.py, where you export your python path'' but i am still confused how to change and export the python path. Here is a detailed explanation of what I did. I followed the instruction in the biaxialSmooth.py by 1- sudo apt install python-escript 2- cd examples/FEMxDEM 3-export PYTHONPATH="/usr/lib/python-escript:/home/weicc/下载/dem-fem-couplinp master/installation/_build/yade/source/examples/FEMxDEM" 4-export LD_LIBRARY_PATH='/usr/lib/python-escript/lib' 5-ln -s '/home/weicc/下载/dem-fem-coupling-master/installation/_build/yade/source/examples/FEMxDEM/yadeimport.py' and it show the worning:'' ln: Could not create symbolic link './yadeimport.py': File already exists Here is the output: Welcome to Yade 2019.01a TCP python prompt on localhost:9000, auth cookie `cyueks' XMLRPC info provider on http://localhost:21000 Running script biaxialSmooth.py ======================================================================= For better performance compile python-escript with direct solver method ======================================================================= Press Enter to continue...
