Word2Vec Sequence contains no matching element #50

Open AdnanSalah84 opened 3 years ago

AdnanSalah84 commented 3 years ago

Hi folks,

I am using word2vec and I have added textfile instead of URL Web Download (text8.zip). The rest of the code is the same as the example written in word2vec.

...............
...............
// code omitted
...............
...............

int wordId = 0;
//text_words = File.ReadAllText($"word2vec{Path.DirectorySeparatorChar}text8").Trim().ToLower().Split();

string textFile = @"c:\...........\MyData.txt";
text_words = File.ReadAllText(textFile).Trim().ToLower().Split();

...............
...............
// code omitted
...............
...............

Here is my sample data text file (MyData.txt) as below:

This is Singapore and one two three four five and Test123 Kings are brave and Queens are beautiful Singapore is a really expensive country but really beautiful country and modern city
This is Malaysia and one two three four five and Test123 Kings are brave and Queens are beautiful Malaysia is a very old country but really beautiful country and old fashion city
This is Singapore and one two three four five and Test123 Kings are brave and Queens are beautiful Singapore is a really expensive country but really beautiful country and modern city
This is Malaysia and one two three four five and Test123 Kings are brave and Queens are beautiful Malaysia is a very old country but really beautiful country and old fashion city

The reading path file is working but I am getting an error message and it says:

I tried many times to fix this issue but still no clue. Could you please help me to solve this issue?

Thanking in anticipation

Can you try to add the sample size to like 100 lines of text at least.
