Need help with running the notebooks from the course Exploratory Data Analysis for Machine Learning

  • 1.  Need help with running the notebooks from the course Exploratory Data Analysis for Machine Learning

    Posted Fri July 22, 2022 09:09 AM
    Hi everyone, 
    I have started learning the course Exploratory Data Analysis for Machine Learning. There are jupyter notebook exercises where I need to read a db file.  I have followed the part where it explains step by step on how to read the sql db file. Apparently, I need to use a function called cos2file as follow (it is given in running jupyter notebooks in IBM Watson Studio part in the course) : 

    def cos2file(p,data_path,filename):
	data_dir = p.project_context.home + data_path 
	if not os.path.exists(data_dir):
		os.makedirs(data_dir)
	open( data_dir + '/' + filename, 'wb').write(p.get_file(filename).read())
    when I try to run this function with arguments as project from my project token, '/data', 'classic_rock.db', The file classic_rock.db is given in the course. I get an error stating. I couldn't figure out what went wrong. Can someone help? 
    NoSuchKey: An error occurred (NoSuchKey) when calling the GetObject operation: The specified key does not exist.
