neo4j - The cypher PROFILE keyword asks for a transaction even if there is already one -

-

i trying profile following query on neo4j server console (community edition, version 1.9.2):

profile start ungrouped=node(1)  create (grouped{__type__:'my.package.grouped'})<-[:has_next]-(ungrouped)  match (ungrouped)-[:leaf]->(leaf)  leaf.`custom-group` groupvalue, grouped, leaf create unique (grouped)-[:group]->({__type__:'my.package.group',groupkey:'group',groupvalue:groupvalue,grouporigin:id(ungrouped)})-[:leaf]->(leaf)  return distinct grouped;

when run above query, message

==> need transaction!

ok, created 1 with

begin transaction ==> transaction started

afterwards run same query again. unfortunately same message again:

==> need transaction!

but there transaction. when type

rollback

the transaction rolled back:

==> transaction rolled

am doing wrong? profiling not work such kind of query design? or bug in neo4j?

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
