Hi,
rootfile_utils.read_tree reads only part of the tree with Python 2.7.11+/ROOT 5.34/19.
Is this expected?
When I execute the following line on the same file, rootfile_utils.read_tree reads
only the first column of the array with Python 2.7.11+/ROOT 5.34/19
I get the correct result with Python 2.7.3/ROOT v5-34-25. See below.
Any hint?
