ymport.textClumps "TypeError"

Asked by Weimin Song

Dear all

         Some clump particles were first generated and exported using export.textClumps, the clumps will be used in another test. When I use export.textClumps to import the clumps to a new test, the following error appears:

TypeError: No registered converter was able to produce a C++ rvalue of type boost::shared_ptr<Body> from this Python object of type tuple

        How should I solve this problem?

       The scripts is here https://www.dropbox.com/sh/l87orgnmxlgf582/AAACFqU2No4qOSyD29r6lfhWa?dl=0

      Thanks in advance!

Hi Weimin,
have a look at doc [1], the loaded particles are already O.bodies.appended

########### some test
...
print len(O.bodies)
clumps = ymport.textClumps("spheres.dat")
print len(O.bodies)
# print clumps # is not "list of spheres" as the docs says, but rather list of (clumpID,[member1ID,member2ID...]), as returned by O.bodies.appendClumped
###########

cheers
Jan
