python - Convert numpy matrix to R matrix and keep it that way -

-

i'd convert numpy matrix r matrix. i'm aware this:

from rpy2 import robjects ro ro.conversion.py2ri = ro.numpy2ri ro.numpy2ri.activate()

and build r matrix:

mat_r = ro.r.matrix(mat_py)

but problem is, whenever refer new matrix in python gets converted numpy matrix. instance, need set row , column names, doing results in this:

mat_r.rownames = numpy.array([1,2,3]) attributeerror: 'numpy.ndarray' object has no attribute 'rownames'

anyone know how can keep shiny new r matrix r matrix, , stop becoming ndarray again?

one way might be

ro.numpy2ri.deactivate()

the conversion can called explicitly (the conversion generics in module, here numpy2ri).

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
