All about PB Files

The PB file type is primarily associated with TensorFlow.

PB	File extension: PB
	File type:	model or image

What is a PB file?

PB files mostly belong to TensorFlow by Google Brain Team. A PB file contains source code written in PureBasic programming language. The contents of this file are saved as text. They include variables, functions, loops etc. Another type of PB file is a trained model used by TensorFlow machine learning and artificial intelligence library. PB is also the filename extension of a dataset containing trip data such as vehicle positions, trip updates, and service alerts used by GTFS Realtime API. Maps and other GIS applications use such PB files to provide trip updates. pprof application profiling tool uses a PB file to store some kind of data.

How to open PB files

You need a suitable software like TensorFlow to open a PB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PB file directly in the browser:. Just drag the file onto this browser window and drop it.

PB file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the PB files comes to the following conclusion:

The PB file extension is very common and includes very many different file formats. However, the following two file formats are common:

15% of all PB files start with the bytes 08 01, which are crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. The files are often between 61 KB and 16 MB in size. It is a modern file type. The files contain the following words: type, value", output", dtype, dtype", resource and type. Some examples of file names are saved_model.pb. These files are attributed to model, saved, input, profile and output.
7% of all PB files internally utilize the GZIP file format. Gzip is a compressed archive file format. Gzip (GNU zip) is only capable of compressing a single file. They consist of illegible, cryptic characters. The files are on average 3 KB in size and range from 380 bytes to 31 KB. The file name 64.pb or 65.pb is characteristic of these files.

All other PB files (78%) have different formats, often, for example, Const, DecodeJpeg, input, normalized, AJA, nput and Placeholder. Sometimes used for graph, frozen, inference, vehicle, positions or data. If you want to find out what your PB file contains, drag and drop it onto this page.

a pb model or image is a special file format by Google Brain Team and should only be edited and saved with the appropriate software.

How to solve problems with PB files

Associate the PB file extension with the correct application.
Update your software that should actually open model or images. Because only the current version supports the latest PB file format. Search, therefore, e.g. on the Google Brain Team manufacturer website after an available TensorFlow update.
To make sure that your PB file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
