TensorFlow – KeyError: “The name ‘import/input’ refers to an Operation not in the graph.

Hey everyone,

Just another small error I’ve run into while testing out Tensorflow’s label image example (Tensorflow/tensorflow/examples/image_retraining/label_image.py):

KeyError: "The name 'import/input' refers to an Operation not in the graph.

This one thankfully doesn’t seem to be my fault. In label_image.py change the following lines:

# Line 78-79
input_layer = "input"
output_layer = "InceptionV3/Predictions/Reshape_1"

# Change to this
input_layer = "Mul"
output_layer = "final_result"

Once that’s done just rerun your script and it should all work. Thanks to the following post for the solution: https://github.com/tensorflow/tensorflow/issues/12736

Tensorflow – No such file or directory

Hey guys,

Just a quick post on how to resolve an error I came across while testing out tensorflow: 

Traceback (most recent call last):
  File "C:UsersChris-PCDesktopimages-to-useattempt2tensorflowexampleslabel_imagelabel_image.py", line 112, in 
    graph = load_graph(model_file)
  File "C:UsersChris-PCDesktopimages-to-useattempt2tensorflowexampleslabel_imagelabel_image.py", line 30, in load_graph
    with open(model_file, "rb") as f:
FileNotFoundError: [Errno 2] No such file or directory: 'tensorflow/examples/label_image/data/inception_v3_2016_08_28_frozen.pb'

All you need to do is download the following file and place it in the directory in the error message: https://storage.googleapis.com/download.tensorflow.org/models/inception_v3_2016_08_28_frozen.pb.tar.gz

Exit Raspberry Pi Camera Preview

Hey everyone,

I ran into a bit of a weird issue with a raspberry pi camera preview today. After starting the preview I hit an uncaught exception which meant that exitPreview was never called.

To get around this use the terminal hotkey and kill the python process. Note that while you won’t be able to see the terminal, it will be running in the background.

Unable to Access RDS Database from Elastic Beanstalk Application

Hey everyone,

I ran into a bit of an issue today where I was unable to access my RDS SQL Express instance from my .NET Elastic Beanstalk instance. I was receiving the following error:

The server was not found or was not accessible.

The solution turned out to be fairly simply thanks to this StackOverflow post: http://stackoverflow.com/a/33207022/522859

Get your server instance security group:
– Log into AWS
– Navigate to elastic beanstalk
– Open your application instance
– Open configuration
– Open instances
– Find “server” on the page and copy the value in the “EC2 security groups” field

Add your server instance security group to your rds rules:
– Navigate to the RDS Dashboard
– Open your RDS instance
– Click on view details (left hand side or top)
– Find Security and Network
– Click on the rds-launch-wizard under security groups
– Click on inbound rules (very bottom currently)
– Add a new inbound rule with the copied security group as the source

Unilateral receiver not allowed in chained payment is restricted – Adaptive Payment DotNet SDK

Hey everyone,

Just an error I ran into today while using the Adaptive Payments SDK for C#/.NET:

Unilateral receiver not allowed in chained payment is restricted

Thankfully this one is fairly simple – one of the receivers hasn’t confirmed their account.

Could not find part of the path ‘C:xlib’ – Adding new Web API Project

Hey everyone,

I ran into the following error when I tried to add a new Web API project in Visual Studio Express 2015 for Web:

Could not find part of the path ‘C:xlib’

The workaround for this was to temporarily unbind the project from TFS: File > Source Control > Advanced > Change Source Control > Click unbind on each of the projects

While not the same problem, this post helped me out: https://github.com/NuGet/Home/issues/1164

This type of fee payer x isn’t recognized by our system – PayPal Adaptive Payments SDK

Hey everyone,

Just another Adaptive Payments SDK error I’ve run into.

Error Id: 560027
This type of fee payer x isn’t recognized by our system

This one is fairly self explanatory, valid values are as follows:

SENDER – Sender pays all fees (for personal, implicit simple/parallel payments; do not use for chained or unilateral payments)
PRIMARYRECEIVER – Primary receiver pays all fees (chained payments only)
EACHRECEIVER – Each receiver pays their own fee (default, personal and unilateral payments)
SECONDARYONLY – Secondary receivers pay all fees (use only for chained payments with one secondary receiver)

This parameter is described in the following documentation: https://developer.paypal.com/docs/classic/api/adaptive-payments/Pay_API_Operation/

Cannot parse *.config file – AdaptivePayments SDK (PayPal)

Hey everyone,

Just working on a small project that uses PayPal’s C# AdaptivePayments SDK. I hit an error while attempting to make the following payment:

var service = new AdaptivePaymentsService();
payResponse = service.Pay(payRequest);
“Cannot parse *.config file. Ensure you have configured the ‘paypal’ section correctly.”

at PayPal.Manager.ConfigManager..ctor()
at PayPal.Manager.ConfigManager.get_Instance()
at PayPal.BasePayPalService..ctor()
at PayPal.AdaptivePayments.AdaptivePaymentsService..ctor()

It turns out that you need to add the following entries to your Web.config:

To get the account information you’ll need to do the following:
– Go to developer.paypal.com
– Login to your sandbox account
– Go to the dashboard
– Select accounts (from the list of all your sandbox accounts)
– Create a new one or select an existing business account
– Click profile
– Click API Credentials

Note that the steps required to get this configuration seem to change all the time. Hopefully this will be enough to get you on the right track.
