import ik error

[lafnac]

hi

i successfully installed ikomia using pip in a virtual env (pycharm + python 3.9). i tried to run the above code and i get many errors. First the line "from ikomia.utils import ik" prodce the following error "Cannot find reference 'ik' in 'init.py'. Other errors are listed bellow the code

from ikomia.dataprocess.workflow import Workflow
from ikomia.utils import ik

wf = Workflow()

resnet = wf.add_task(ik.train_torchvision_resnet(
model_name="resnet34",
batch_size="16",
epochs="5"
),
auto_connect=True
)

dataset_folder = "/home/train/"

wf.run_on(folder=dataset_folder)

/home/resnet/resnet-ikomia.py

During handling of the above exception, another exception occurred:

================================================================================================

same errors with this code too

from ikomia.dataprocess.workflow import Workflow
from ikomia.utils.displayIO import display

wf = Workflow()

canny = wf.add_task(name="ocv_canny", auto_connect=True)

wf.run_on(url="https://raw.githubusercontent.com/Ikomia-dev/notebooks/main/examples/img/img_work.jpg")

display(canny.get_input(0).get_image())
display(canny.get_output(0).get_image())

Environment:

• Debian 11
• Python version 3.9
• Ikomia API version 0.10.0

any suggestion please?
many thanks.

Hi @lafnac,

It seems that libusb-1.0.so is missing from your OS. This library is required because it's a dependency inherited from OpenCV. We try to include as many dependencies as possible, but some may be missing on some Linux distributions.

So as a first step to your issue, install the libusb-1.0:
sudo apt-get install libusb-1.0-0-dev

As it could be the root cause, let me know if you still have errors then.

On my end, Ubuntu 20+, Python 3.10, I needed to install several more libraries to run this code:

from ikomia.dataprocess.workflow import Workflow
from ikomia.utils.displayIO import display

# Init your workflow
wf = Workflow()

# Add the Canny Edge Detector
canny = wf.add_task(name="ocv_canny", auto_connect=True)

# Run on your image
# wf.run_on(path="path/to/your/image.png")
wf.run_on(
    url="https://raw.githubusercontent.com/Ikomia-dev/notebooks/main/examples/img/img_work.jpg"
)

# Inspect your results
display(canny.get_input(0).get_image())
display(canny.get_output(0).get_image())

These libraries were needed:

apt install libsm6
apt install libthai0
apt install libegl1-mesa-dev
apt install libharfbuzz0b
apt install libglu1-mesa-dev

Then the example ran successfully.
