QUESTION
When I have been running the Caliper V0.4.2 for measuring the benchmarks of Fabric 2.1.0 1.4.7, I got the below error
...ANSWER
Answered 2022-Mar-07 at 12:36Looks like you are using the main branch of caliper-benchmarks. I would suggest you https://github.com/hyperledger/caliper-benchmarks/blob/main/networks/fabric/README.md
From what you have posted, you should use the latest available version of caliper which is 0.4.2, not 0.4.0. To do so the command you should issue is
QUESTION
I conducted prospensity score matching in R using the R-package "Matching" and "Matchit" respectively, but the number of matches were completely different.
The dataset is here http://web.hku.hk/~bcowling/data/propensity.csv or http://web.hku.hk/~bcowling/examples/propensity.htm.
example <- propensity
The code using "Matching" was：
m.ps <- glm(trt ~ age + risk + severity, family="binomial", data=example)
example$ps <- predict(m.ps, type="response")
PS.m <- Match(Y=example$death, Tr=example$trt, X=example$ps, M=1, caliper=0.2, replace=FALSE)
summary(PS.m )
ANSWER
Answered 2022-Feb-22 at 17:02Two reasons: 1) Matching proceeds through the matches in the order of units in the dataset while MatchIt by default proceeds through matches based on descending order of the propensity score, and 2) Matching uses a nonzero distance tolerance by default, meaning that any two units with a propensity score difference of .00001 or less will be considered exactly matched, whereas MatchIt has no such tolerance.
To ensure the results are the same between Matching and MatchIt, set m.order = "data" in matchit() and set distance.tolerance = 0 in Match().

ANSWER
Answered 2022-Feb-07 at 20:53As @cls said you are comparing a float to the string 'e1' in (df.CALIPER > 'e1'). You need to compare df.CALIPER to float( e1.get() ). I don't have access to your files so I've not shown a second gui just a print statement. As the first GUI will be destroyed after the quit e1.get() must be executed before destroying the application with the result stored for later access.

I have two selects in my project, one is car categories and subcategories, from which value i am sending to the server.
my problem is storing valueCarPartSubCategory it stores all id, and creates only one array.

QUESTION
I've got Caliper configured as a subtree of my custom Fabric blockchain. I have it configured correctly in order to connect the network and am running a small set of tests at the moment. The arguments I'm providing are absolutely correct in terms of the custom chaincode being run, but whenever I try to create a transaction via Caliper I get the error:
Failed to perform submit transaction [CreateAsset] using arguments [], with error: TypeError: Cannot read property 'status' of undefined
Anybody encountered this before with Caliper V0.4.2? It's interfacing with a Fabric 2.3.3 instance on local machine via Kubernetes, with the latest SDK bound.
The error occurs on line 237 of transactions.js inside the node_module fabric-network, where there is a strict property comparison on a commit object.
Also it's worth noting that the querying part of my test rounds is yielding expected results... none of those assets get created due to the error thrown, and when querying for a given asset an error like so occurs:
Failed to perform query transaction [ReadAsset] using arguments [], with error: Error: error in simulation: transaction returned with failure: Error: The asset does not exist
The closest thing I've been able to find is this ~2 year old issue which isn't exactly what I'm facing but it's the same sort of error at least... any help or pointers would be greatly appreciated because I'm struggling to glean useful information.

I am trying to create a facet_grid that contains histograms for measurements for three different measuring methods for three different objects. However, my code returns a fourth "(all)" graph.
How can I remove the (all) graph and return a 3x3 facet_grid with the clavicle, phalanx, and sacrum as the columns, and calipers (cm), ruler (in), and your knuckle as the rows?
The following is a sample data frame and the ggplot2 code to create the histogram facet_grid.

I have two test tests, one reading and one writing on the blockchain. I'm getting two different errors, one at the start of the test and one at the writing test. The reading test is working normally without problems.
Initial error:
...ANSWER
Answered 2021-Dec-21 at 21:56From the network file you posted a couple of points
- you can't define any nodes in it (for example you've added orderers). They are ignored
- you've specified that your connection profile is a dynamic profile by setting discover to true in your network file, this means it will use discovery to determine the network topology and may not use the nodes you have explicitly defined in your connection profile. If you want to be explicit in your connection profile (and thus define a static connection profile) like you have in your above example, you should set
discoverto false, which hopefully will solve your problem.
As a side note, if you use discovery then the node-sdk (used by caliper) and caliper by default converts all discovered node hosts to localhost, which is why you see it trying to contact localhost. To disable this see Runtime settings in https://hyperledger.github.io/caliper/v0.4.2/fabric-config/new/

I have developed a system using Hyperledger Fabric peer version 2.2.2 hence I need to test the performance (i.e. latency, throughput etc.) of this system using Hyperledger Caliper. I'm new with Blockchain and found it hard to integrate my network with Caliper! Which version of caliper will be suitable for fabric 2.2.2? How can I carry out this whole integration procedure?

I am trying to write a function that iterates over a vector using map2(), but which also takes another input which is fixed on each call.
For example, this code takes just the one input, vars:
ANSWER
Answered 2021-Nov-12 at 15:05If I have understood correctly I don't think you should use map2 here. As @Limey mentioned you can include data as argument in the function.
