Word2Vec: System.AccessViolationException

ZedZipDev commented 3 years ago

The unhandled System.AccessViolationException occurs , and I my try/catch cannot catch it. What is the reason? How to fix it?

        public bool Run()
        {
            PrepareData();

            var graph = tf.Graph().as_default();
            tf.train.import_meta_graph($"graph{Path.DirectorySeparatorChar}word2vec.meta"); //<---------Exception

System.AccessViolationException
  HResult=0x80004003
