OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized.

1. Created a virtual environment; conda create -n anomalib_env
2. conda activate anomalib_env
3. pip install anomalib
4. anomalib install
   ERROR: Could not find a version that satisfies the requirement torch<2.2.0,>=2+cpu (from versions: 2.2.0, 2.2.0+cpu, 2.2 No matching distribution found for torch<2.2.0,>=2+cpu
   Error in 4 is overcome by pip install lightning
5. copy-pasted the code listed in "Training" section of Anomalib webpage [1]. However the code runs into a error listed below,

OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized.
OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results.

Restarting kernel...

[ghost]

Issue is resolved. Follow the following sequence of steps in Anaconda command prompt.

conda create -n anomalib_env
conda activate anomalib_env
pip install anomalib
anomalib install
pip install lightning
pip install torchvision
pip install opencv-python
pip install imgaug
pip install kornia
pip install pandas
pip install scikit-learn
pip install timm
pip install einops
pip install FrEIA
pip install open_clip_torch

[samet-akcay]

Ideally, anomalib install should install the rest of the packages above. Are you sure that it did not install them?

[ghost]

Yes, the additional libraries were not installed. We had to install the packages listed above.
