<p>The above is the error reported by the program. How can I solve this problem?Is the cause of this error related to CV2 and skimage modules? I need to read and process the image in the program</p>

ptrblck: <p>Could you try to isolate the error and post a reproducible code snippet?<br>
The stack trace points to some <code>skimage</code> and <code>cv2</code> methods, but it’s unclear to me, how this error is caused.</p>

lzkzls: <p>I didn’t find a feasible solution in the forum. What would cause this error? Is my program leaking memory? Or something?</p>

<p>Thanks for your reply! Maybe, i couldn’t give you a reproducible code snippet, because it contains multiple .py files. I am reproducing an academic paper on face animation, in which grid data is used to train neural network. The structure of neural network is a generator and three discriminators, which are trained by the method of GaN. When reading data, I used skimage.io.imread () function. This error will be reported when the model is trained for about 2000 rounds. Can you give me some guidance, please? How can I position this problem.</p>

ptrblck: <p>You could try to (hopefully) get another backtrace using</p>
<pre><code class="lang-auto">$ gdb --args python my_script.py
...
Reading symbols from python...done.
(gdb) run
...
(gdb) backtrace
...
</code></pre>
<p>but from the current stack trace I don’t know, how to debug further besides trying to isolate the issue with a minimal code snippet.</p>

lzkzls: <p>When I use skimage.io.imread (), the error was resolved. Using CV2.imread() causes segmentation fault.</p>
