Unexpected error

Hi Abdulrahman!

First, I recommend you to restart Kernel, clear the output cells, and then try re-executing the code again after ensuring all the required files are in the same location.

Kernel >> Restart and Clear Outputs

If this doesn't help, you can create a new notebook and do the procedure again from the start. 

Here are some alternative approaches if this doesn't solve the problem:

Ensure the current working directory of your Jupyter Notebook matches the location of the file using the following lines of code:

import os
print(os.getcwd())

 If the output directory is incorrect, set it to the correct one:

os.chdir('path_to_your_directory')
print(os.path.exists('speech_01.wav'))

 or use the variable's name as done in the lessons (file_path ).

Furthermore, you can try to use an absolute path to specify its location. 

result = model.transcribe('C:/path_to_file/speech_01.wav')

I hope this helps. Feel free to get back to us if the problem persists. 
Best,
Ivan
