The following code works fine

<pre><code class="python">
small_img = cv2.resize(img, (ncols, nrows))
</code></pre>



But if it is called in a function like:

<pre><code class="python">
def my_resize(img):
small_img = cv2.resize(img, (ncols, nrows))
my_resize(img)
</code></pre>

It crashes python.exe
