The constructor calls the to_networkx_graph function which attempts to guess the input type and convert it. When I tried readtable, it gets the information but doesn't save it as a number, so potentially I could transform the table to a matrix, but I haven't been able to. Today it is possible to obtain genome-wide transcriptome data from single cells using high-throughput sequencing (scRNA-seq). Mac OS X: brew install libdmtx. read_csv uses pandas.
