WebWhat you do is split the data in 8 equal part i.2 200 files each. Now write a function that loads the model object, and run inference on the 200 files. At last using multiprocessing create 8 worker process and parallelize the function on 8 chunk of your 1600 files. This way you would only load the model only 8 times in each process. WebThis causes that Sklearn and Pytorch use the same thread pool, which in my opinion is the desired behavior. Another solution would be to compile PyTorch from source. I'm not sure why PyTorch is shipping it's own libgomp. I'm guessing it's for compatibility reasons on older systems, that don't have libgomp or an outdated/incompatible version.
