Failed to create .traineddata file from box and tif for Indonesian license plate

[reza4836]

Greetings Matt, I have an issue when executing the last step for training Indonesian country with openALPR. In the train-ocr rep, the last step ("Training the OCR") describes that we have to execute the "train.py" to generate .traineddata file (in my case would be lid.traineddata if success) from .box and .tif file. From this step, I completely stuck because this program gives 'permission denied' error in the tessdata directory, even if I already changed the permission state by chmod in order to give permission of train.py to change, read, and write the tessdata directory.

Here's the directory from code:

TESSERACT_DIR='/media/gspeintercon/GSPE1/GIT/tesseract-4.0.0-beta.1'
os.environ["TESSDATA_PREFIX"] = '/media/gspeintercon/GSPE1/GIT/tesseract-4.0.0-beta.1'
os.system("export TESSDATA_PREFIX=" + '/media/gspeintercon/GSPE1/GIT/tesseract-4.0.0-beta.1')
TESSERACT_BIN= '/media/gspeintercon/GSPE1/GIT/tesseract-4.0.0-beta.1/tessdata'
TESSERACT_TRAINDIR= '/media/gspeintercon/GSPE1/GIT/tesseract-4.0.0-beta.1/training'

Here's the error result:

Can you help me where was my error cause, I tried it with another country which the box and tif file was available from the repo but still can't generate the .traineddata file and gives same error. Thank you.
