ModuleNotFoundError: No module named 'yolox' ?? how can i resolve it ? please!

[jcyhcs]

hi,professor:

i test use cmd liks this:
python3 tools/demo.py image -n yolox_tiny -c ../weights/yolox_tiny.pth.tar --path ../assets/dog.jpg --conf 0.3 --nms 0.65 --tsize 640 --save_result

BUT! I GOT ERROR:
result
Traceback (most recent call last):
File "tools/demo.py", line 14, in
from yolox.data.data_augment import preproc
ModuleNotFoundError: No module named 'yolox'

OH, please tell me why? help ,please!

Hi, @jcyhcs. May I ask if you were able to solve the issue? If yes, how?

I am currently experiencing the same problem:

Traceback (most recent call last):
  File "tools/train.py", line 10, in <module>
    from yolox.core import Trainer, launch
ModuleNotFoundError: No module named 'yolox'

Thank you!

Thank you!

Was able to find a quick fix, I manually exported my work directory and ran the train script again (on Jupyter notebook):

!export PYTHONPATH="${PYTHONPATH}:/your/path/to/project/" && python tools/train.py -f exps/example/yolox_voc/yolox_voc_s.py -d 1 -b 32 --fp16 -o -c ../yolox_s.pth

Here's the actual line I have used:

!export PYTHONPATH="${PYTHONPATH}:/home/jupyter/tutorials/yolo_x_trial/YOLOX/" && python tools/train.py -f exps/example/yolox_voc/yolox_voc_s.py -d 1 -b 32 --fp16 -o -c ../yolox_s.pth

Hello,

I have the same problem when Trying to run the UniTrack demo.

Traceback (most recent call last):
File "demo/mot_demo.py", line 27, in
from detector.YOLOX.tools.demo import Predictor
File "/home/cesiro/Desktop/UniTrack/detector/YOLOX/tools/demo.py", line 14, in
from yolox.data.data_augment import preproc
ModuleNotFoundError: No module named 'yolox.data'

And it did not resolve itself with your fix. Any idea? @arianyambao

Same here @tulbureandreit @arianyambao

python tools/demo.py video -n yolox-s -c .\weights\yolox_l.pth --path 0 --conf 0.25 --nms 0.45 --tsize 640
Traceback (most recent call last):

@KashaMalaga hello,
I thiink you would find your solution here
Zhongdao/UniTrack#12

Also, please check your paths for everything you open when executing demo.py! And the files ( i had some missing files)

First of, please make sure you decide for a version of CUDA and consistently use that; I am using 11.3 in this.
I fixed this and many other installation and compilation errors, by uninstalling and re-installing the following programs in the exact order

1. Clone the yolox repo and unzip it
2. Install Virtual Studio 2019 Community (https://visualstudio.microsoft.com/downloads/)
3. Download CUDA https://developer.nvidia.com/cuda-11.3.0-download-archive (I just did express installation)
4. Get https://docs.conda.io/en/latest/miniconda.html for your version of python
5. Install pytorch with cuda enabled conda install pytorch torchvision cudatoolkit=11.3 -c pytorch
6. Navigate conda to the download directory (cd yolox_path) of yolox and type in:
   - pip install -r requirements.txt
   - pip install pycocotools # this should get added to requirements.txt @FateScript
   - pip install -v -e . # or python setup.py develop
7. Congratulations you fixed the error, now you'll be able to run yolox as described in Quick Start > Demo (example: python tools/demo.py video -n yolox-s -c /path/to/your/yolox_s.pth --path /path/to/your/video --conf 0.25 --nms 0.45 --tsize 640 --save_result --device [cpu/gpu] )

A couple notices:

• You can at the time of writing this; not install above CUDA 11.3, because conda does not provide a higher version in sources to compile with pytorch
• You can not install a higher version of Virtual Studio, because of incompability with CUDA (devs did not add support for MSVS22 yet)
• You're forced to install MSVS; because this repo depends on it, to be able to compile as written in step 6.
• You can not simply uninstall conda, because it removes its CUDA compiled pytorch version and that in return breaks yolox. But I think you could most likely avoid this

In short you kept getting this error, because you couldn't compile yolox properly or not at all.

Getting this error while running

train.py

[manish33scss]

yeah i know its late but,
add
import sys
sys.path.append("..")
just before
from yolox.data.data_augment (etc)
in demo.py, it'll work

@manish33scss I tried your solution but still not able to resolve
