I ' m converting JSON data into a pandas table, but I still need to convert datetime string to a float so that the mplfinance interpreter is able to read and plot the data. But there is an issue with one of the packages in the interpreter when trying to execute the code. Does anyone know why the updated version of mpl_finance doesn' t have this date2num package (as far as I know)?.
