Training

Bug

Training does not take place if the --multi-scale option is activated. Stops directly in the first epoch at the beginning.

@DP1701 your error message clearly states RuntimeError: CUDA error: out of memory.

YOLOv5 🚀 can be trained on CPU, single-GPU, or multi-GPU. When training on GPU it is important to keep your batch-size small enough that you do not use all of your GPU memory, otherwise you will see a CUDA Out Of Memory (OOM) Error and your training will crash. You can observe your CUDA memory utilization using either the nvidia-smi command or by viewing your console output:

CUDA Out of Memory Solutions

If you encounter a CUDA OOM error, the steps you can take to reduce your memory usage are:

Reduce --batch-size
Reduce --img-size
Reduce model size, i.e. from YOLOv5x -> YOLOv5l -> YOLOv5m -> YOLOv5s > YOLOv5n
Train with multi-GPU at the same --batch-size
Upgrade your hardware to a larger GPU
Train on free GPU backends with up to 16GB of CUDA memory:

AutoBatch

You can use YOLOv5 AutoBatch (NEW) to find the best batch size for your training by passing --batch-size -1. AutoBatch will solve for a 90% CUDA memory-utilization batch-size given your training settings. AutoBatch is experimental, and only works for Single-GPU training. It may not work on all systems, and is not recommended for production use.

Good luck 🍀 and let us know if you have any other questions!

@DP1701 👋 hi, thanks for letting us know about this possible problem with YOLOv5 🚀. If batch -1 causes issues then I'd suggest you don't use it.

Symbadian · 2023-01-16T09:42:40Z

Hi @DP170, I am running a GPU can you guide me on how you initiated the GPU device, please?
was there something in the code that you amended and which aspect of the code was this?

I am trying to run my GPU via a Linux server and it's proving extremely challenging!

Thanx for acknowledging my digital presence in advance

DP1701 · 2023-01-16T10:01:59Z

HI @Symbadian,

You don't have to change anything in the code. The following command in the terminal is sufficient:

(For mulit-gpu training)

python3 -m torch.distributed.launch --nproc_per_node NUMBER_OF_GPUs train.py --data path_to_your_data --img image_size --weights weights --batch batch_size --epochs number_of_epochs --device number_of_devices

The information in bold is information to be provided. Important: The stack size must be greater than 0 when using multi-GPU training.

It is important that you have installed Pytorch with CUDA support. Otherwise it will not work.

Symbadian · 2023-01-16T10:05:29Z

@DP1701 hi pal, I wish that was the case! this is my error with the torch library and I am not sure how to solve this!

ERROR: Could not find a version that satisfies the requirement torchvision>=0.8.1 (from versions: 0.1.6, 0.1.7, 0.1.8, 0.1.9, 0.2.0, 0.2.1, 0.2.2, 0.2.2.post2, 0.2.2.post3)

Symbadian · 2023-01-16T10:15:59Z

@DP1701 I ran this code and it came back with
launch.py: error: unrecognized arguments: --nproc_per_node 4 train.py --data coco128.yaml --img
where can I find the repo download that you are using?
Can you guide me to such, please?

DP1701 · 2023-01-16T10:40:15Z

What packages do you have installed?

pip3 list

Try this:

python3 train.py

Does it work?

Symbadian · 2023-01-16T10:42:40Z

@DP1701 hey pal, I manage to install the necessary pytorch

and I ran the next bits (python3 train.py) I got a new error

I am now trying to find out what that is and how to solve this...I am not sure this is problematic!!!
In the read-me file, I followed all the instructions line by line...

and still, these errors persist...

DP1701 · 2023-01-16T11:02:09Z

Uninstall torch and torchvision.

Then type in:

pip3 install torch torchvision

Symbadian · 2023-01-16T11:08:56Z

still pal, $ python3 train.py Traceback (most recent call last): File "/home/MattCCTV/YOLO9Classes/yolov5/train.py", line 42, in <module> import val as validate # for end-of-epoch mAP File "/home/MattCCTV/YOLO9Classes/yolov5/val.py", line 37, in <module> from models.common import DetectMultiBackend File "/home/MattCCTV/YOLO9Classes/yolov5/models/common.py", line 23, in <module> from utils.dataloaders import exif_transpose, letterbox File "/home/MattCCTV/YOLO9Classes/yolov5/utils/dataloaders.py", line 31, in <module> from utils.augmentations import (Albumentations, augment_hsv, classify_albumentations, classify_transforms, copy_paste, File "/home/MattCCTV/YOLO9Classes/yolov5/utils/augmentations.py", line 13, in <module> import torchvision.transforms.functional as TF ModuleNotFoundError: No module named 'torchvision.transforms.functional'; 'torchvision.transforms' is not a package

DP1701 · 2023-01-16T11:17:24Z

Do you still have torchvision 0.1.8 installed?

Symbadian · 2023-01-16T11:50:18Z

Yes I do!! But it’s still giving me and an error.. Cheers to positive perspectives! Matt.

Install this:

But uninstall torch and torchvision beforehand.
Torchvision 0.1.8 is out of date.

Ahh I see.. ok will trying that.. Cheers to positive perspectives! Matt.

@DP1701 got this error:

DP1701 · 2023-01-16T12:36:08Z

Here are all the version:

Link

You have to check which system, which python version, which Cuda version you have installed.

You could also try just:

pip3 install torch==1.12.0
pip3 install torchvision==0.13.0

Python >=3.7, <=3.10 is required

Symbadian · 2023-01-16T12:41:30Z

@DP1701 Yip, went through those already..
None of them seems to be working for me...
Hence, I tried the torchvision 0.1.8 and that seems to be the only one that's working

Symbadian · 2023-01-16T12:42:48Z

Can you guide me to the repo?
So that I can get the latest files for processing..
This cannot be the right way for the installs... I am getting too many errors at this stage..

DP1701 · 2023-01-16T12:44:20Z

You need at least torchvision>=0.8.1 for YOLOv5.

Symbadian · 2023-01-16T12:47:08Z

@DP1701 I would have to agree with you here! but it or they rather is not installing no matter what I do!
I have been trying to get these installs for two weeks now and every day I am faced with the same challenge!

Maybe I should just update the repo files and be done with it???!!!

DP1701 · 2023-01-16T13:22:37Z

If by repo files you mean the files from YOLO, then nothing will change. Alternatively, you could try miniforge (Conda): Link.

After the installation, create a new environment with:

conda create --name YOLOv5 python=3.9.13
conda activate YOLOv5

Then install Pytorch with the Conda instruction

DP1701 · 2023-01-16T13:23:22Z

And then install the rest that YOLOv5 needs with pip

Symbadian · 2023-01-16T13:28:42Z

@DP1701 Ok will try that now..

Symbadian · 2023-01-16T14:34:03Z

conda create -name YOLOv5 python=3.9.13

Hi @DP1701 I got this:

Collecting package metadata (current_repodata.json): done

DP1701 · 2023-01-16T14:38:09Z

insert a second - character before name:

conda create --name YOLOv5 python=3.9.13

Symbadian · 2023-01-16T14:39:19Z

ok will try that now
it took quite a while to delete the files from the GPU server, my apologies

  File "/home/MattCCTV/YOLO9Classes/yolov5/train.py", line 29, in <module>
    import torch
ModuleNotFoundError: No module named 'torch'```

may I request some guidance on the torch command that I should apply here, please?

My confidence is a tad low, I thought I had an idea, but it seems like it's more tricky than expected!

Thus far, I have been unsuccessful with my selection of the torch..

DP1701 · 2023-01-16T14:48:52Z

You must first install torch and torchvision with Conda if you have installed and activated the environment correctly. Take a look at the link to Pytorch that I sent you today.

Symbadian · 2023-01-16T15:05:00Z

@DP1701 I see but when I check out the compatibility pytorch/pytorch#47776

Torch doesn't work well here??!!!??!
WIth this
conda create --name YOLOv5 python=3.9.13 ???!!!

SO I tried
conda install -c pytorch-lts torchvision

AND I GOT THE ERROR BELOW*

to be incompatible with the existing python installation in your environment:

Specifications:

  - torchvision -> python[version='>=3.8,<3.9.0a0']

Your python: python==3.9.12

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

The following specifications were found to be incompatible with your CUDA driver:

  - feature:/linux-ppc64le::__cuda==10.2=0
  - feature:|@/linux-ppc64le::__cuda==10.2=0

Your installed CUDA driver is: 10.2```
