couldn't find components in fine tuned traineddata file

[Surya VaraPrasad Alla]

when using the fine tuned model, addressed below error:

(1, "read_params_file: Can't open tessedit_char_blacklist=,;: Error: Tesseract (legacy) engine requested, but components are not present in tesstrain/data/eng_pcb/eng_pcb.traineddata!! Failed loading language 'eng_pcb' Tesseract couldn't load any languages! Could not initialize tesseract.")

fine tuned model(below is the comment at the end of training, looks successful):
At iteration 393/10000/10017, Mean rms=0.188%, delta=0.284%, char train=1.149%, word train=2.877%, skip ratio=0.3%,  New worst char error = 1.149 wrote checkpoint.

Finished! Error rate = 1.116

Help:
Can someone look at what is missing in here?
