So yeah… that seems conclusive, I will happily settle with saying the issue is in the DLL, and that pytest actually suffered no regression (on the contrary).

Short Description

I’m using PyCharm and am writing a pytest unit test.
I can run the test normally but if I try to debug it the debugger crashes.

Windows fatal exception: access violation

Issue

I’m using pytest to run some tests for my project. Sometimes (about 30 to 50%) I get an error after the test finished. But this is preventing the testengine to create the testreport, which is really a pain.

Has somebody any idea how to fix or debug that?

I’m using pytest 5.4.1 with python 3.8.0 on win10. But this is also reproducable with older pytest versions.

The plugin plugin_zigbee_dongle.py uses pyserial (3.4) to communicate with an usb-rf-dongle in a thread. The following code is a snippet of this plugin:

import serial
import threading

class ZigbeeDongleSerial(object):

    def __init__(self, test_engine):
        self.ser = serial.Serial()
        self.test_engine = test_engine

    # ----------------------------------------------------------
    def connect(self,
                port,
                baud,
                timeout):

        self.ser.baudrate = baud
        self.ser.timeout = timeout
        self.ser.port = port
        self.ser.open()
    
    # ----------------------------------------------------------
    def disconnect(self):

        try:
            if self.is_connected():
                self.ser.close() # <------- This is line 141 ----------
        except:
            pass

# ----------------------------------------------------------
# ----------------------------------------------------------
class PluginZigbeeDongle(PluginBase):

    # ----------------------------------------------------------
    def __init__(self, test_engine):
        super(PluginZigbeeDongle, self).__init__()

        self.test_engine        = test_engine
        
        self.dongle_serial = ZigbeeDongleSerial(self.test_engine)

        self._startup_lock = threading.Lock()
        self._startup_lock.acquire()

        self.reader_thread = threading.Thread(target=self._read_worker, name="ZigbeeDongleThread")

    # ----------------------------------------------------------
    def start(self):
        super(PluginZigbeeDongle, self).start()

        # connect the serial port
        self.dongle_serial.connect()

        # start the reader thread
        if self.dongle_serial.is_connected():
            self.reader_thread.start()

    # ----------------------------------------------------------
    def stop(self):
        super(PluginZigbeeDongle, self).stop()

        # disconnect the serial port
        if self.dongle_serial.is_connected():
            self.dongle_serial.disconnect() # <------- This is line 232 ----------

        # stop the reader thread
        if self.reader_thread.is_alive():
            self.reader_thread.join()

    # ----------------------------------------------------------
    def _read_worker(self):

        # start-up is now complete
        self._startup_lock.release()

        # handle the incoming character stream
        done = False
        while not done:

            try:
                c = self.dongle_serial.read_byte()

            except serial.SerialException:
                done = True

            except AttributeError:
                done = True

            if not done:
                self._read_parser(c)

Solution

Downgrading pyserial from Version 3.4 to Version 2.7 fixed the problem

import pytest
from pywinauto.application import Application

def test_case():
    assert True

This is my script.

This is the result.

I just wonder how that fatal exception occurs and how we can fix it.

The Source code is:

import cv2
# used for accessing url to download files
import urllib.request as urlreq
# used to access local directory
import os
# used to plot our images


pic = "dataset/face.jpg"


# read image with openCV
image = cv2.imread(pic)

# plot image with matplotlib package
image_rgb = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)
image_gray = cv2.cvtColor(image_rgb, cv2.COLOR_BGR2GRAY)

haarcascade = "dataset/cascade.xml"
detector = cv2.CascadeClassifier(haarcascade)
faces = detector.detectMultiScale(image_gray)
for face in faces:
#     save the coordinates in x, y, w, d variables
    (x,y,w,d) = face
    # Draw a white coloured rectangle around each face using the face's coordinates
    # on the "image_template" with the thickness of 2 
    cv2.rectangle(image_rgb,(x,y),(x+w, y+d),(255, 255, 255), 2)

#cv2.waitKey(0)
#cv2.destoyAllWindows()

LBFmodel = "dataset/lbfmodel.yaml"

landmark_detector  = cv2.face.createFacemarkLBF()
landmark_detector.loadModel(LBFmodel)
_, landmarks = landmark_detector.fit(image_gray, faces)

It is a simple Face detector app in OpenCV but I wanter to add Facial landmark mark detection in this…
everything works fine until I add the last three lines of code which crashes the whole app

Also, I am using python 3.6.7 and purposefully downgraded the version of opencv to 3.4.6.

«Windows fatal exception: access violation» when calling decimate #229

Description

Example Data

I can reproduce it with this file:

The text was updated successfully, but these errors were encountered:

This seems related to pyvista/pyvista#861. @pyvista/developers, this is concerning that we’ve had two Windows users recently report the Windows fatal exception: access violation error.

@nidu, can you please share a PyVista report (you shared a scooby default report which doesn’t show details about PyVista)? print(pv.Report(gpu=False)) ( gpu=False to avoid any errors)

My immediate advice, I suspect you are using the latest version of VTK (9.x). Please try downgrading VTK to 8.1.2 and see if the error happens still

Here’s the info from pv.Report(gpu=False)

Hi, small update. I could set up WSL 2 on my machine, installed pyvista there, but i get similar error with the example above, so probably it’s not Windows specific (if WSL 2 is a good enough approximation to Linux).

And indeed this simple piece of code works fine:

but this one crashes with access violation (notice one more face)

Thanks for looking into this @nidu! Many of the pyvista developers/maintainers have been busy with our day jobs, so sorry for the late follow-up.

It appears that running clean fixeds this sort of problem:

We can consider adding a note to decimate indicating that segmentation faults can be prevented by running clean beforehand. I’m hesitant to run clean always since it can take a long time to execute.

@akaszynski thanks, clean is much cleaner than what i came up with!

Tensorflow train.py throws Windows fatal exception

I’ve been working with Tensorflow for quite a while now, had some issues, but they never remained unresolved. Today i wanted to train a new model, when things got interesting. At first, the training stopped after one step without any reason. It happend before, opening a new cmd window solved it. Not this time tough. After i tried again, train.py started to throw this:

Last time i saw this issue, it was because i was using data downloaded from the internet, and there was one particular picture that TF did not like, but removing that one from the dataset solved the issue. I was wondering if this was the case, but no. I couldnt start it with previously tried datasets either. i decided to reinstall tensorflow, set up a new virtual environment, but still nothing. Been looking for hours what the problem could be, both on the internet, and on my own trying different things, but nothing worked, same exception each time. Did anybody encounter anything similar?

Training object detection with model_main.py fails with Windows fatal exception: access violation

I am trying to train an object detection model with model_main.py file. I can train this on ubuntu environment without any problem, but now moved to win 10 (because I have in that PC a GeForece 1080Ti) and now I have trouble. Training can start and does pretty well until the first checkpoint where I get these errors (also I can restart and it continous training from last checkpoint, but fails again after saving the next. ):

FIX: Exception Access Violation Error on Windows 10

milan

So, what is Exception access violation error and how to fix it? According to the reports, Exception access violation error is usually related to a memory error.

It’s mostly caused by software, but sometimes this error can be caused by a faulty RAM module.

Exception Access Violation error can be problematic, and speaking of errors, users reported the following error messages on their PC:

How can I fix the Exception Access Violation error?

1. Check your PC for malware

According to users, sometimes this error can appear due to malware infections. Many of them reported a fake Chromium browser on their PC that causes this error to appear.

Therefore, it’s advised to perform a detailed scan with your antivirus software. If your current antivirus can’t find and fix the problem, we strongly recommend that you try another solution.

In search for the right antivirus for your system, you should look for the one that has a minimal impact on the system, identity safety features, and strong virus protection.

BullGuard

BullGuard is a one-stop solution to scan for malware. No Exception Access Violation errors will bother you again!

2. Add Data Execution Prevention Exception

If a specific program is giving you an Exception access violation error, you might want to add that program to the Data Execution Prevention exceptions list. To do that follow the steps above.

Once you add the desired application to the exclusion list, check if the problem is resolved.

3. Disable User Account Control

It has been reported that Exception access violation error occurs when users are trying to install Java or when they try to run Java applets or applications.

In order to fix this issue, it’s advised to temporarily disable User Account Control. To do that, follow the instructions above.

This solution applies to other software as well, so even if Java is working without any problems on your computer, you can try disabling User Account Control to fix this issue.

We have to mention that disabling User Account Control comes with slight security risk, so if you’re not comfortable with it, just disable User Account Control when you run the desired application and then turn it back on.

4. Create options.ini file

As we already mentioned, the Exception access violation error affects all sorts of software, and video games aren’t an exception.

One game affected by this issue is Lord of The Rings: Battle for Middle Earth, but fortunately for you, there’s a solution available.

Keep in mind that this solution works only for Lord of The Rings: Battle for Middle Earth, however, you can change the configuration file for most games by following similar steps.

5. Make sure that the file isn’t set as read-only

Sometimes Exception access violation error can appear because your files are set to read-only mode. However, you can change that by following the above steps.

This is a simple solution and several users reported that it works, so feel free to try it out.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.
Click here to download and start repairing.

6. Reconnect your headset

This error has been reported by Vindictus players, and according to them, this error occurs with Logitech headset G35, but the issue might be related to other headsets from other manufacturers as well.

According to users, the only solution is to unplug your headset while the game is loading and plug it back in once the game has loaded.

Also, if you find out that the problem was caused by the headphones, you can find a better pair in our list with the best headphones.

7. Check for hardware problems

As we already mentioned Exception access violation error can sometimes be related to your RAM memory, so it won’t hurt to check if your RAM memory is working properly.

You can check your memory using MemTest86. Just download it, and move it to a USB flash drive, restart your computer and let MemTest86 run for a while.

If you don’t know how to do it, maybe it’s best that you contact a professional and ask him to do it for you.

Many users reported that their RAM was the cause of this error, so be sure to check your RAM and replace it if you find any problems with it.

You can also find more about your PC components with the software from this convenient list.

7. Use the Compatibility mode

If you’re getting Exception Access Violation error message frequently on your PC, that can be due to compatibility issues. Certain older applications aren’t fully compatible with Windows 10.

Fortunately, Windows has a useful feature called Compatibility mode that allows you to run older applications. If you have this problem with a certain application, simply enable Compatibility mode.

Once you make the necessary changes, try starting the application again and check if the error reappears.

Keep in mind that you might have to try several different compatibility modes before you find the one that works on your PC.

8. Run the Hardware troubleshooter

According to users, you might be able to fix this problem simply by running the Hardware troubleshooter.

This feature is designed to fix common hardware problems, and it might help you with Exception Access Violation error.

Once the troubleshooter is finished, check if the problem still appears. Few users reported that this solution worked for them, so feel free to try it out.

9. Reinstall the application

If you’re getting Exception Access Violation while trying to run a certain application, you might be able to fix the problem simply by reinstalling that application.

Simply remove the problematic application from your PC and install it again. If possible, try to download and install the latest version and check if that solves the problem.
