Problem:<\/strong><\/p>\n

In batch mode, when I run my PyTecplot script using Python 3.8+ on Windows, I receive an error stating that:<\/p>\n

tecplot.exception.TecplotLibraryNotFoundError: The Tecplot batch library or one of its dependencies could not be found...<\/tt><\/p>\n

What is causing this error?<\/p>\n<\/div>\n

<\/div>\n

Solution:<\/strong><\/p>\n

It is likely that you are using an out-of-date version of PyTecplot.<\/p>\n

Using PyTecplot in batch mode with Python 3.8 on Windows 10 requires version 1.1 or later. Python 3.8 changed the way dynamic libraries are loaded as described here<\/a> in Python’s documentation.<\/p>\n

To fix this problem, update PyTecplot to the latest version. Typically, this involves running the following command:<\/p>\n

pip install --upgrade pytecplot<\/pre>\n
See the PyTecplot documentation for more detailed updating instructions for Windows<\/a>,\u00a0Linux<\/a>, or\u00a0MacOS<\/a>. To get the current version of PyTecplot, run the following in the Python interpreter:<\/p>\n
import tecplot\r\nprint(tecplot.__version__)<\/pre>\n
