问题
Greetings,
I have come across an interesting error and was wondering if anyone knew the cause.
I create several numpy arrays of dtype object and wish to initialize them with empty strings, so I did the following to create them:
txtInputs=empty((7,12), dtype=object)
txtInputs[:, :]=''
repeated...
How they are used after is not relevant other than that these variables are local to the function and are gone when it returns. However, I have discovered that when I call the function that does this many times in a row, my program crashes with an error saying pythonw.exe has stopped working. This crash is consistent and happens after a specific number of calls, and that number never changes.
However, if I replace the second line with:
txtInputs.fill('')
It will not crash. What is wrong with using [:,:]='' to fill the numpy array??
Thank you.
PS. I am using python 2.5 and numpy 1.0.4
回答1:
This error does not occur with numpy 1.5.1. We were fixing quite a few bugs around the time of numpy 1.0.4, particularly with the object and string dtypes. This is probably one of them. The bug has apparently been fixed since then.
