Python API

[mobeeniqbal101]

Hi, I am trying to run some python examples, but I am unable to do so. I checked Build python while doing the Cmake-configuration and I can also see the following folder, but whenever I try to run I get the following error stating "cannot import pyopenpose"

Executed Command (if any)

Note: add --logging_level 0 --disable_multi_thread to get higher debug information.

python2 01_body_from_image.py --logging_level 0 --disable_multi_thread

OpenPose Output (if any)

Errors (if any)

Error: OpenPose library could not be found. Did you enable BUILD_PYTHON in CMake and have this Python script in the right folder? cannot import name pyopenpose

Your System Configuration

1. Whole console output (if errors appeared), paste the error to PasteBin and then paste the link here: LINK

2. OpenPose version: Latest GitHub code? Or specific commit (e.g., d52878f)? Or specific version from Release section (e.g., 1.2.0)? 1.7.0

3. General configuration:

   • Installation mode: CMake, sh script, manual Makefile installation, ... (Ubuntu); CMake, ... (Windows); ...?
   • Operating system (lsb_release -a in Ubuntu): Ubuntu
   • Operating system version (e.g., Ubuntu 16, Windows 10, ...): Ubuntu 18
   • Release or Debug mode? (by default: release):
   • Compiler (gcc --version in Ubuntu or VS version in Windows): 5.4.0, ... (Ubuntu); VS2015 Enterprise Update 3, VS2017 community, ... (Windows); ...?

4. Non-default settings:

   • 3-D Reconstruction module added? (by default: no):
   • Any other custom CMake configuration with respect to the default version? (by default: no):

5. 3rd-party software:

   • Caffe version: Default from OpenPose, custom version, ...?
   • CMake version (cmake --version in Ubuntu):
   • OpenCV version: pre-compiled apt-get install libopencv-dev (only Ubuntu); OpenPose default (only Windows); compiled from source? If so, 2.4.9, 2.4.12, 3.1, 3.2?; ...?

6. If GPU mode issue:

   • CUDA version (cat /usr/local/cuda/version.txt in most cases):
   • cuDNN version:
   • GPU model (nvidia-smi in Ubuntu):

7. If CPU-only mode issue:

   • CPU brand & model:
   • Total RAM memory available:

8. If Python API:

   • Python version: 2.7, 3.7, ...?
   • Numpy version (python -c "import numpy; print numpy.version.version" in Ubuntu):

9. If Windows system:

   • Portable demo or compiled library?

10. If speed performance issue:

The following python folder is present in the build folder, but the error is still appearing:

During Building process following warning appears again and again:

_/content/openpose/3rdparty/caffe/include/caffe/util/cudnn.hpp: In function ‘const char* cudnnGetErrorString(cudnnStatus_t)’: /content/openpose/3rdparty/caffe/include/caffe/util/cudnn.hpp:21:8: warning: enumeration value ‘CUDNN_STATUS_VERSIONMISMATCH’ not handled in switch [-Wswitch] switch (status) {

It seems to be the same Problem than in issue 2157 ([https://github.com/CMU-Perceptual-Computing-Lab/openpose/issues/2157]) - a version missmatch between Cuda and cuDNN.

I am running it on Google Colab and since the warning appears the python skripts do not work anymore.

I am facing the same issue. Any solution yet?

[mobeeniqbal101]

You need to check advanced settings while building via the cmake gui, it has to do with python3 vs python2 difference.

I made it work by running !apt install --allow-change-held-packages libcudnn8=8.1.0.77-1+cuda11.2 afterwards, in order to use compatible CUDA and cuDNN versions. Not sure how this worked but I'm okay with dark magic sometimes.
