Python float array to file

If so, what is the right way to convert into their 'actual' value? I am using lumpy for speed and I don't prefer struct. What uint really should be uint8 - 1 byte unsigned integer rather than the full 8 byte version? Still a fortuitous mismatch in dtypes could explain a fromfile read that runs but produces wrong values, especially ones that look way off.

I'd suggest using this dt1 , and using it to load just one record. See if the values look reasonable. If 'g' is float this length is poorly defined; it should be an int of some sort. If you have left fn open at this point, then np.

I would start with a small n just to see if this is promising, and later try a larger value or the open ended In other words, you description sounds like the file contains a header of fixed size, and then a variable size block of floats.

This code assumes that mylist is of the format [ So, it will only print one row Then, somehow in your code, you iterate through something and at each iteration, you define mylist as a 2-element list — Julien Spronck.
