  1. fix Scala kernel

    The Scala kernel isn't working, making it difficult to get some hands on experience on labs that use the Scala kernel, eg. all of the Spark labs.

    Thank you

  2. Create database/tables in Hive using ssh to systemt.datascientistworkbench.com

    Good Day,

    I ssh systemt.datascientistworkbench.com. Then I start hive using "hive" command. I try to create database/tables in hive but it says I don't have access.

    I see many test kind of hive databases which people have created. How can I create database/tables in hive?

    Please advise.

    Thanks.

    -Shakeel

  3. Errors in the data

    = df[["horsepower","curb-weight","engine-size","highway-mpg"]]
    lm.fit(Z,df["price"])
    Yhat = lm.predict(Z)

    There is an error as it shows Yhat = lm.predict(X) and this is incorrect. must be Z

  5. Use downloaded data instead of external site for the lab

    Data Visualization with Python lab data from external site incorrect. Suggest you to download a fixed format data to your drive for the lab

  16. Show/suggest learning/skill paths

    Group courses to define graduation series from foundation to expert. For example, I completed a foundation or introductory course which should be a prerequisite to a more advanced course, I should know which one to take next.

  18. ABOUT the data visualization with python

    here is your dataset--->The DataFrame dfcan = pd.readexcel('https://ibm.box.com/shared/static/lw190pt9zpy5bd1ptyg2aw15awomz9pu.xlsx', sheetname='Canada by Citizenship', skiprows=range(20), skipfooter=2 )

    rr
    But acually,python can't not work and also crashed;here i download the file and cancel the(dropdown list) set ,and i upload to my box cloud,so here you can go to download in this URL (https://app.box.com/s/zkd6hlp15nr38581ew0kifswwncaacwr), and you have to check out what cloumns have and to decide to use .drop method

    and now, when you download file finished and use df=pd.readexcel( your filepath,sheetname=' Canada by Citizenship (2)', skiprows=range(20), skip_footer=2)
    ) BY THE WAY,your filepath is different…

  20. Advanced course paths similar to other platforms

    We need more hands on experience and intermediate ad advanced level courses like coursera offers for free because it's quite expensive..! This platform is very different when compared to those because we have the proof to showcase our talents immediately after we finish our final test..! And all the courses are free..😊
