Fix issues on import joblib and pd.concat

[jaimeam]

Dear Udacity team,
I'm working through the Machine Learning Engineering Nanodegree course and found a couple of bugs to be fixed while working on the first mini-project IMDB Sentiment Analysis - XGBoost (Batch Transform).ipynb.

• Issue ImportError: cannot import name 'joblib' #16
• pd.concat method would not work as it is done now with lists and Numpy arrays inputs, because it requires Pandas objects as input

Please have a look at it, let me know if it makes sense and if there is anything else where I can help, and let's fix the issues so the students are not disrupted by them.
Thank you
Jaime

@jaimeam Thanks for fixing this issue.
It did suddenly appear for me today (was not an issue 4 days ago) and I was totally at a loss what was wrong :)

Hello all, I'm very pleased to see that this has been fixed, and yes, I also faced this issue in the mini-project 😃

I can vouch for that solution; it worked for me!

$ python
Python 3.9.2 (default, Mar  3 2021, 15:03:14) [MSC v.1916 64 bit (AMD64)] :: Ana
conda, Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import joblib
>>>

Looking forward to when this gets merged in 😁

Hi markplotlib,
This error is occuring when I deploy my model in sagemaker. I am confused how to go in terminal as I am using notebook inside sagemaker.
