Error how can i resolve it

[brmarkus]

Can you provide more details, please?
Which sample, which file(s) are you working with and see the compilation problem? Are you following a blog from "Learn-OpenCV", if yes, which?
Do you have more console output?

It looks like you need to install "http://torch.ch/".

[brmarkus]

So you are running this JupyterNotebook, "https://github.com/spmallick/learnopencv/blob/master/Object-Tracking-and-Reidentification-with-FairMOT/Tracking_using_FairMOT.ipynb", right?

Are you sure you have executed the second cell, and it finished successfully?

# Clone the FairMOT repository, and instell the required libraries.
!git clone https://github.com/ifzhang/FairMOT.git
!pip install torch==1.7.0 torchvision==0.8.0
!pip install cython
!pip install -r FairMOT/requirements.txt

It installs "torch" (in version v1.7.0), which contains the header "TH/TH.h".

[brmarkus]

Can you provide more details, please?
Is there a chance that you can share what results you get from each cell?

If you open "https://github.com/spmallick/learnopencv/blob/master/Object-Tracking-and-Reidentification-with-FairMOT/Tracking_using_FairMOT.ipynb" in a separate browser window in parallel to what you are running in your Colab environment?

Which of the cells look different?
The original version of this JupyterNotebook is more than 2 years old... your environment might have newer versions of some of the components; not all dependencies in this JupyterNotebook has an explicit version number...

[brmarkus]

Yes i am running this code no this line doesnt exectued .updated version is downloaded not this one
…

Can you provide more details, please?

Which line do you mean, can you split the multiple lines into separate lines and execute each line separately - and then show the results you are getting?

[brmarkus]

From e.g. "https://pypi.org/pypi/torch/json", a recent version seems to be "2.2.2".

$>pip index versions torch
torch (2.2.2)
Available versions: 2.2.2, 2.2.1, 2.2.0, 2.1.2, 2.1.1, 2.1.0, 2.0.1, 2.0.0, 1.13.1, 1.13.0, 1.12.1, 1.12.0, 1.11.0, 1.10.2, 1.10.1, 1.10.0, 1.9.1, 1.9.0, 1.8.1, 1.8.0, 1.7.1

As the code of this sample is old, don't try the latest version.

Try with e.g.

!pip install torch==1.7.1

Any solution as i am encountering same problem

[brmarkus]

Can you provide more details, please? The same missing header-file?
Where you able to install an older version (the notebook is quite old, there were a lot of updates to the dependencies in the meantime).

[brmarkus]

I needed to modify a few cells:

remove version numbers:

# Clone the FairMOT repository, and instell the required libraries.
!git clone https://github.com/ifzhang/FairMOT.git
!pip install torch torchvision
!pip install cython
!pip install -r FairMOT/requirements.txt

and

using a different repo and different branch name:

# Clone and install DCNv2.
%cd /content/FairMOT
%rm -rf /content/FairMOT/DCNv2
!git clone -b pytorch_2.0.1 https://github.com/lbin/DCNv2
%cd /content/FairMOT/DCNv2
!chmod +x ./make.sh
!./make.sh

import sys
sys.path.append('/content/FairMOT/DCNv2')

and

comment-out a download (doesn't exist anylonger):

# Download all the trained FairMOT models.
!mkdir -p /content/FairMOT/models
%cd /content/FairMOT/models/
!gdown --fuzzy https://drive.google.com/file/d/1MEvsRPyoAqYSCdKaS5Ofrl7ZfKbBZ1Jb/view

How far do you get with those changes?

[brmarkus]

(I needed to apply some smaller modifications inside two Python files in FairMOT/src/lib/tracker/ due to numpy deprecated the type np.float; so wherever np.float was used in the sources I changed it to np.double)
(the used video file consists of 1500 frames; processing all frames in Google colab can take quite a long time... processing at around 9fps...)

(when changing files used in the Jupyter notebook, then I needed to restart the Google colab runtime manually so that the modified Python files would be used)

Inside the Google Colab notebook I modified these files:
from FairMOT: "src/lib/tracker/matching.py" and "src/lib/tracker/multitracker.py" (cloned https://github.com/ifzhang/FairMOT/blob/master/src/lib/tracker/matching.py and
https://github.com/ifzhang/FairMOT/blob/master/src/lib/tracker/multitracker.py)
=> every np.float I changed to np.double

The files can be opened and modified inside the colab.

I'm getting this, finally:

This Jupyter notebook (its used dependencies) need some updates to get it working again, now in the year 2024... it was created long time ago and with the dependencies outdated in the meantime...

[Tech3467]

i am encountring this error at the last line

[brmarkus]

Looks like something went wrong cloning the repo "https://github.com/ifzhang/FairMOT/" in cell number 2:

# Clone the FairMOT repository, and instell the required libraries.
!git clone https://github.com/ifzhang/FairMOT.git

The method LoadVideo can be found in the repo here: "https://github.com/ifzhang/FairMOT/blob/master/src/lib/datasets/dataset/jde.py#L86"

Have you applied changes to files (or deleted, moved, renamed files&folders) and repos in your notebook environment (locally? Google-Colab?)?
You might need to start with a fresh environment.
If you run cells multiple times, then e.g. Git doesn't clone the repo again (error message like "there is already a non-empty-folder").

You might need to add a "delete folder" instruction to the cells which clone repos, e.g.

# Clone the FairMOT repository, and instell the required libraries.
!rm -rf FairMOT
!git clone https://github.com/ifzhang/FairMOT.git
... ...

[brmarkus]

You might try a more recent implementation... this notebook's dependencies need some updates...

You might try something like this:

• https://github.com/openvinotoolkit/openvino_notebooks/blob/latest/notebooks/person-tracking-webcam/README.md
• https://github.com/openvinotoolkit/openvino_notebooks/blob/latest/notebooks/person-counting-webcam/README.md
