Instructions

1. Clone the repository and navigate to the downloaded folder.

   	git clone https://github.com/udacity/aind2-dl.git
   	cd aind2-dl
   

2. Obtain the necessary Python packages, and switch Keras backend to Tensorflow.

   For Mac/OSX:

   	conda env create -f requirements/aind-dl-mac.yml
   	source activate aind-dl
   	KERAS_BACKEND=tensorflow python -c "from keras import backend"
   

   For Windows:

   	conda env create -f requirements/aind-dl-windows.yml
   	activate aind-dl
   	set KERAS_BACKEND=tensorflow
   	python -c "from keras import backend"
   

   For Linux:

   	conda env create -f requirements/aind-dl-linux.yml

aind2-dl's Issues

Discrepancies in requirements and yaml files

I just forked and cloned this repo and created the conda environment per the readme.
I then launched the Student_Admissions.ipynb and the very first code block returned an error stating that there is no 'pandas' module.

Checking the aind-dl-windows.yml file, I see that there is nothing for pandas in the list, although it is in the requirements.txt list. Is there a way to load the requirements list that I missed? There are some other discrepancies as well.

If it's just adding the requirements specifications to the .yml file, should I make the changes and submit a pull request?

feature request: Remove 'rank' 0 from Student_Admissions.ipynb

Remove the pointless 'rank 0' input feature

2. Process the data:

# remove rows with NANs or 'rank' = 0
data = data.dropna(0)
data = data[data['rank']>0]
...

4. Define the model architecture

...
model.add(Dense(128, activation='relu', input_shape=(6,)))
...

Packages missing in current linux-64 channels

• appnope 0.1.0 py35_0
• appscript 1.0.1 py35_0
• python.app 1.2 py35_4
• xlwings 0.10.2 py35_0

This is happening when creating the conda environment.
Can somebody help with this? I am on Ubuntu 15.04

Typo in Student_Admissions.pynd

In cell 4 in Student_Admissions.pynb, the last line is y = keras.utils.to_categorical_data. I believe it should be np_utils.to_categorical.

resolved packages not found

I am running ubuntu 16.04 when i create try to create an environment using says

conda env create -f requirements/aind-dl-mac-linux.yml
it gives
ResolvePackageNotFound:
appnope 0.1.0 py35_0
when i remove the package dependency from the yml file it gives me the same error for a few others
on removing all the error throwing dependencies it says
UnsatisfiableError: The following specifications were found to be in conflict:
jpeg 9b 0
qt 5.6.2 0 -> jpeg 8*
