size mismatch for Prediction.bias Error!

[Chiyan200]

This code is used
import easyocr
reader = easyocr.Reader(['ta'], gpu=False) # this needs to run only once to load the model into memory
result = reader.readtext('tamTxt.png')
print("result : ",result)

i got this error i run this code using cpu
