Field to load .pb file

edit

"i want" is not enough, to help you, we would need:

• an explanation, what you're trying to achieve with it
• opencv / tf versions
• a link to the training code, and the generated model, and possibly a pbtxt file to look at here.
• an exact description, what you're doing to get it from tf to cv::dnn
• your test code

please edit your question and add required information there
