Encounter this UTF-8 Error when I try to import Pandas

Question

I am a novice and picking up DS using python. I used the latest Anaconda package and tried to import pandas in Jupyter. Then I encountered following error message. I tried to install Pandas package again with conda command but it didn't resolve this issue. Thanks for any advice in advance.

If you are using Mac OS X, try adding the following lines to your ~/.bash_profile:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

Thanks for the tips. But I can't locate this bash_profile when i type that in spotlight. Sorry, I am no programmer and this is foreign to me. – Ghostintheshell May 30 '16 at 11:50
Should be in your `home` directory, the one that has your user name. It may not exist yet - here's an explanation of how to create one: https://natelandau.com/my-mac-osx-bash_profile/ – Stefan May 30 '16 at 11:55
Were you able to resolve the issue? – Stefan May 31 '16 at 12:37
Yes, I got it handled. Many many thanks. Interesting to note. That only happens on my Macbook, not my Macbook Pro. Both are using El Captain system and updated to the latest version of Anaconda. But somehow they performed differently and the pandas version is different as I recalled. I don't know why. Is that a problem because I installed some non-conda package like mlestack, PyMC, etc using pip. And I also have Canopy version of Python installed. I am just baffled by their different performance. – Ghostintheshell May 31 '16 at 14:27
It pays to get familiar with `bash`, the `Terminal` app. The `Mac OS` accesses python versions based on a `PATH` variable that you can also set in `.bash_profile`. If you as `which python` in `Terminal`, you'll see which `python` version the system will access first. If you have `pip` installed, you can also do `pip freeze` to see the current list of packages and versions. Take a look at `homebrew` to install software other than python packages, and at `virtual environment` to manage python installations. – Stefan May 31 '16 at 14:54
Thanks for all the tips and I really have to check out and understand everything you mentioned here. So, what you are trying to say is even I installed many different libraries that may or may not be handled by Conda I can still set up path at bash file so that my juypter notebook under the anaconda folder can still access. Is that the gist? Now I regret that I should study CS instead of business admin. – Ghostintheshell Jun 03 '16 at 16:08
Anaconda usually modifies the `PATH` so that the system considers it the first `python` to look for, and `pip install` will install under anaconda python, so your packages should be available. `which python` in terminal will tell you which `python` installation the system looks for first. If that is not the one you want to use, you need to modify `PATH` in your `.bash_profile`. This is all separate from your original question on the language settings, though. – Stefan Jun 03 '16 at 16:14
Got it. Will try out when I am working on my ML exercise next time. Many thanks for all the tips. – Ghostintheshell Jun 04 '16 at 13:08
