Installed numpy today, here is the output: Like this answer is showing you can use genfromtxt instead. Find centralized, trusted content and collaborate around the technologies you use most. When dtype=None, the type of each column is determined iteratively from itself (see below). corresponding keys can be column indices (integers) or column names It is actually a method of NumPy and not its array, let us understand it through the example given below, where we actually perform the append operation on a numpy list. The option dtype=None is provided for convenience. dtype, the missing names will be defined with this default template: We can overwrite this default with the defaultfmt argument, that default dtype is dtype=None, meaning that the types of each column and False otherwise.

Please use skip_header instead. In the following example, the second column is converted from as string for missing data: converters = {3: lambda s: float(s or 0)}. In that case, each item is associated to a column, in order. In addition to genfromtxt, the numpy.lib.npyio module delimiter to a single integer (if all the columns have the same The converters can also be used to provide a default value for these missing entries.
