Machine Learning Hooks - Object Detection & Face Detection

Post by mjalafoo » Wed Apr 07, 2021 10:26 am

Hi There,

I am facing a challenge with getting the OBJECT DETECTION and FACE DETECTION to function. I followed the guidelines documented and rebuilt the system multiple times without luck. I have the following versions installed:
- ZoneMinder v1.34.23
- Event Server v6.1.19
- Python 3.8.5
- OpenCV v4.5.2-dev
- Perl v5.30.0

When I run the following command sudo -u www-data /var/lib/zmeventnotification/bin/ :

Code: Select all

INF [zm_train_faces] [Setting up signal handler for logs]
INF [zm_train_faces] [Switching global logger to ZMLog]
Traceback (most recent call last):
  File "/var/lib/zmeventnotification/bin/", line 12, in <module>
    import as train
ModuleNotFoundError: No module named ''
Below is a sample log when the following command sudo -u www-data /usr/bin/ --debug is run and an event is triggered:

# if yes, last detection will be stored for monitors
# and bounding boxes that match, along with labels
# will be discarded for new detections. This may be helpful
# in getting rid of static objects that get detected
# due to some motion. 
# The max difference in area between the objects if match_past_detection is on
# can also be specified in px like 300px. Default is 5%. Basically, bounding boxes of the same
# object can slightly differ ever so slightly between detection. Contributor @neillbell put in this PR
# to calculate the difference in areas and based on his tests, 5% worked well. YMMV. Change it if needed.
# Note: You can specify label/object specific max_diff_areas as well. If present, they override this value
# example: 

# this is the maximum size a detected object can have. You can specify it in px or % just like past_det_max_diff_area 
# This is pretty useful to eliminate bogus detection. In my case, depending on shadows and other lighting conditions, 
# I sometimes see "car" or "person" detected that covers most of my driveway view. That is practically impossible 
# and therefore I set mine to 70% because I know any valid detected objected cannot be larger than that area

# setting to yes is recommended to avoid filling up space
# keep to no while debugging/inspecting masks
# Note this does NOT delete debug images later

# If yes, will write an image called <filename>-bbox.jpg as well
# which contains the bounding boxes. This has NO relation to

# Typically, if you enable delete_after_analyze you may

# This section gives you an option to get brief animations 
# of the event, delivered as part of the push notification to mobile devices
# Animations are created only if an object is detected
# NOTE: This will DELAY the time taken to send you push notifications
# It will try to first creat the animation, which may take upto a minute
# depending on how soon it gets access to frames. See notes below


# If yes, object detection will attempt to create 
# a short GIF file around the object detection frame
# that can be sent via push notifications for instant playback
# Note this required additional software support. Default:no

# Format of animation burst
# valid options are "mp4", "gif", "mp4,gif"
# Note that gifs will be of a shorter duration
# as they take up much more disk space than mp4

# default width of animation image. Be cautious when you increase this
# most mobile platforms give a very brief amount of time (in seconds) 
# to download the image.
# Given your ZM instance will be serving the image, it will anyway be slow
# Making the total animation size bigger resulted in the notification not 
# getting an image at all (timed out)

# When an event is detected, ZM it writes frames a little late
# On top of that, it looks like with caching enabled, the API layer doesn't
# get access to DB records for much longer (around 30 seconds), at least on my 
# system. animation_retry_sleep refers to how long to wait before trying to grab
# frame information if it failed. animation_max_tries defines how many times it 
# will try and retrieve frames before it gives up

# if animation_types is gif then when can generate a fast preview gif
# every second frame is skipped and the frame rate doubled
# to give quick preview, Default (no)

# You can now run the machine learning code on a different server
# This frees up your ZM server for other things
# To do this, you need to setup
# on your desired server and confiure it with a user. See its instructions
# once set up, you can choose to do object/face recognition via that 
# external serer

# URL that will be used
# API/password for remote gateway

# config for object

# If you are using legacy format (use_sequence=no) then these parameters will 
# be used during ML inferencing

# If you are using the new ml_sequence format (use_sequence=yes) then 
# you can fiddle with these parameters and look at ml_sequence later
# Note that these can be named anything. You can add custom variables, ad-infinitum

# quick overview: 
# num_jitters is how many times to distort images 
# upsample_times is how many times to upsample input images (for small faces, for example)
# model can be hog or cnn. cnn may be more accurate, but I haven't found it to be 


# This is maximum distance of the face under test to the closest matched
# face cluster. The larger this distance, larger the chances of misclassification.
# When we are first training the face recognition model with known faces,
# by default we use hog because we assume you will supply well lit, front facing faces
# However, if you are planning to train with profile photos or hard to see faces, you
# may want to change this to cnn. Note that this increases training time, but training only
# happens once, unless you retrain again by removing the training model
#if a face doesn't match known names, we will detect it as 'unknown face'
# you can change that to something that suits your personality better ;-)

# Many of the ALPR providers offer both a cloud version
# and local SDK version. Sometimes local SDK format differs from
# the cloud instance. Set this to local or cloud. Default cloud

# -----| If you are using plate recognizer | ------

# If you want to host a local SDK
# Plate recog replace with your api key
# if yes, then it will log usage statistics of the ALPR service
# If you want to specify regions. See
# minimal confidence for actually detecting a plate
# minimal confidence for the translated text

# ----| If you are using openALPR |-----

# For an explanation of params, see
# openalpr returns percents, but we convert to between 0 and 1

# ----| If you are using openALPR command line |-----


# Do an alpr -help to see options, plug them in here
# like say '-j -p ca -c US' etc.
# keep the -j because its JSON

# Note that alpr_pattern is honored
# For the rest, just stuff them in the cmd line options

## Monitor specific settings

# Examples:
# Let's assume your monitor ID is 999
# my driveway

# Advanced example - here we want anything except potted plant
# exclusion in regular expressions is not
# as straightforward as you may think, so 
# follow this pattern
# object_detection_pattern = ^(?!object1|object2|objectN)
# the characters in front implement what is 
# called a negative look ahead

# object_detection_pattern=^(?!potted plant|pottedplant|bench|broccoli)

# polygon areas where object detection will be done.
# You can name them anything except the keywords defined in the optional
# params below. You can put as many polygons as you want per [monitor-<mid>]
# (see examples).

my_driveway=306,356 1003,341 1074,683 154,715

# You are now allowed to specify detection pattern per zone
# the format is <polygonname>_zone_detection_pattern=<regexp>
# So if your polygon is called my_driveway, its associated
# detection pattern will be my_driveway_zone_detection_pattern
# If none is specified, the value in object_detection_pattern 
# will be used
# This also applies to ZM zones. Let's assume you have 
# import_zm_zones=yes and let's suppose you have a zone in ZM
# called Front_Door. In that case, all you need to do is put in a 
# front_door_zone_detection_pattern=(person|car) here

ModuleNotFoundError: No module named ''

This would suggest either the module is missing or is not in the default location. Have you checked the location of the file

This seems to be a bug in the already captured by the developer.
That's a bug. Please update to master of zmeventnotification
(commit fix: ... 6d09d1d070)
However, now after applying the bug fix (I haven't updated to master, I just applied the fix in the, the problem goes away, but the process ends with KILLED as shown below:

Code: Select all

INF [zm_train_faces] [Setting up signal handler for logs]
INF [zm_train_faces] [Switching global logger to ZMLog]
INF [zm_train_faces] [Ignoring monitor specific settings, as you did not provide a monitor id]

Any idea what am I doing wrong?
Is it something with the structure of the KNOWN_FACES folder?
Please note I do not hace yet (faces.dat) generated inside KNOWN_FACES forlder.
