numpy#genfromtxt raise an IOError while the txt file is empty

Question

Then genfromtxt method of numpy load an ndarray from a text file. However, if the text file is empty, the method would raised an IOError while I expected an empty ndarray:

IOError: End-of-file reached before encountering data.

Is there any solution to get an empty ndarray if the text file is emtpy?

Answer 1

Try using a try block to return an empty array on error:

try:
    a = np.genfromtext("filename.txt")
except IOError:
    a = np.array([]) # Or np.empty or np.zeros...
