  • 1.  How to export a csv file from Notebook running in Watson Studio

    Posted Mon February 24, 2020 08:56 AM
    I am running a python notebook in IBM Watson Studio. I can read data files in to work on, but how I export my dataframe as a csv file when I'm finished? I have searched all over the place, but can't find anything.

    Hi Ben,

    Try this link: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_csv.html

    In Watson Studio, you can export the running Notebook as a CSV file using the following steps:

    Open your Notebook and make sure the code cell you want to export is active.
    In the menu bar, select File > Export > Export as CSV.
    In the pop-up "Export as CSV" dialog box, you can select the range of cells to export, as well as additional options to export, such as output header rows or output format.
    Click the "OK" button to start the export process.
    The exported CSV file will be saved in the directory you choose, usually in the same directory where you ran the Notebook.
    Please note that the exported CSV file will contain the output results of the selected cells in the Notebook. Ensure that you review and modify the cells before exporting to obtain the desired data format.

    For that you need to import 'Project' library.  The project token is an authorization token that is used to access project resources and Watson framework will help will you to do this and there is a  page in net how to do this.

    After importing, the code will look like:

    from project_lib import Project
    project = Project(project_id='51d8ac9e-9bf9-4369-bfcc-46e2715df873', project_access_token='p-b0f3e2e30e5bc80a9f07d89a838fbc2ea1eebeaa')
    pc = project.project_context

    After above step is done, just export the dataframe to csv file like:

    project.save_data(data=dataframe.to_csv(index=False),file_name='ADNIMERGE_ETL.csv',overwrite=True)

    What happens to a file that is just exported without project association?

    dataframe.to_csv('filename.csv')

    Thanks

    That was the first thing I tried. I have no idea where the file goes, but I can't locate it within the project, or assets.

    Hi Ben,

    Are you trying save the file  locally? If so will have to create a function that will provide a download link to save your df to your machine.

    Hello Ben,

    For your reference please go through the Watson studio documentation page as mentioned below:

    Hello Ben,

    I am using Watson studio ML for decision optimization. I have used the below code to get the dataframe output. It's working fine.

    My variable name was ProductionPlan (which is multi-index) tuple. Then I convert the tuple list to dataframe. Please go through the below code, which might be helpful for you to get the right dataframe output which is ProductionPlanReport in the below mentioned sample python code.

    if mdl.solve():
        mdl.float_precision = 3
        print("Optimization model has Solution")
        mdl.print_solution()

       outputs = {}

       df_BlendProd = pd.DataFrame({'ProductionPlan': ProductionPlan})
       df_BlendProd.index.names=['MixingUnit','Blend','Period']
       df_BlendProd=df_BlendProd.ProductionPlan.apply(lambda v: v.solution_value)
       df_BlendProd = df_BlendProd[df_BlendProd >0]
       outputs['ProductionPlanReport'] = df_BlendProd.reset_index()

    You can use something like this:

    df.to_csv('file_name.csv', sep=';', encoding='utf-8',index = False)


    If you want (,) instead of (;) as a separator just change the "sep" option. You can find more information in the Pandas documentation. If you want it indexed, it's the default option, you may remove the last option.

    Hope it helps

    Use  df.to_csv() method to export your dataframe to CSV 

    It save you your file in current directory

    df = pd.DataFrame({'name': ['Raphael', 'Donatello'], 'mask': ['red', 'purple'], 'weapon': ['sai', 'bo staff']})
    df.to_csv(index=False)

    See this for reference

    Hi Ben,

    Here is a simple example:

    However, I have just discovered that I cannot find the file test_out.csv in any of my buckets.
    => So who can tell me where the file is placed for unqualified save operations?

    try in that way:

    import pandas as pd
    df.to_csv("file_name", index=False)

    # "file_name" - replace on title your file​ which you wish

    Everyone,

    We are all in agreement that df.tocsv() exports to the current directory.

    However, what does this mean within the context of Watson Studio?

    I went through my buckets and cannot find any file saved this way, only the one saved using project.save_data().
    So where does it go? Is it in memory and is lost as soon as the kernel stops, or what?

    Thank you

    what does this mean within the context of Watson Studio?

    As I per primitive understanding, 'Watson Studio' has object storage / cloud storage. Traditional python API 'to_csv' method cannot write to this storage. The  'project' library method 'helps export to the  'Watson Studio' specific cloud storage.  This file then visible to all notebooks assets belonging to the same project workspace.

    Now, another notebook can read this already exported file, say 'ADNIMERGE_processed.csv' stored in 'Watson Studio' context/cloud storage:

    df=pd.read_csv(project.get_file('ADNIMERGE_processed.csv'))

    See the answer from Manash Sarma for the method that works. Except use your own 'project id','access token' that were generated manually by going to project settings and adding, if they aren't created when you input the data. To find the output file, go to the cloud storage, find the instance that supports the notebook and it should be in that bucket. A bucket is just a section of the storage that holds the project and related files.

    You may have to use the project.save_data based on the below mentioned mentioned if you'd like to store it as an asset. However if you use to_csv, the file gets stored in the project but may be not as a data asset. 

    To download it., go to Project - Add and Find data button (in the right top corner) - Use Files and you should be able to locate it there.

    if you run from your notebook !pwd you will find the path where the file is stored locally, you can see it with !ls

    you can use the to_csv() method from the pandas library. Here's an example of how to do this:

    import pandas as pd
    
    # Create your DataFrame
    df = pd.DataFrame({'name': ['Alice', 'Bob', 'Charlie'], 'age': [30, 25, 22]})
    
    # Export the DataFrame to a CSV file
    df.to_csv('my_data.csv')
    

    This will create a CSV file called my_data.csv in the same directory as your notebook. You can then download the CSV file to your local machine by clicking on the file in the Watson Studio file magazine and selecting the "Download" option.

    In IBM Watson Studio, you can export a DataFrame to a CSV file using the standard pandas method. If you have a DataFrame named df  and you want to export it to a CSV file, you can use the following code:

    import pandas  as pd 

    # Export DataFrame to CSV 

    # following file path -> ('path//to//your//file.csv')

    Assuming your data is stored in a DataFrame called 'df'. Also, replace 'data.csv' with the desired file name
    import pandas as pd
    df.to_csv('data.csv', index=False)
