I'm attempting to run GPU Acceleration during training using the OpenCL libraries.
I have built tesseract to use openCL, and installed the NVidia Compute driver 440 on my Ubuntu 19.10 installation Whenever I run tesstrain.sh, however, I run into the issue that the program refuses to select the proper GPU. Rather than use my NVidia GeForce GTX 1060 6GB device, it will select the CPU as my default OpenCL device even though it detects my GPU, and scores it better in the built-in benchmark. Setting TESSERACT_OPENCL_DEVICE=1 seems to do nothing as nvidia-smi shows that the process is not utilizing my GPU. Here is my tesstrain.sh output: === Starting training for language 'eng' > [Tue 18 Feb 2020 04:55:13 PM PST] /usr/local/bin/text2image > --fonts_dir=/usr/share/fonts --ptsize 12 --font=Chit >
