QUESTION
I'm working with large data (~25million points) in Python in Jupyter Notebook and want to have an interactive graph that also doesn't take forever to load. Using Bokeh gives me the interactivity and Holoviews and Datashader allows the data to be graphed relatively quickly.
Python: 3.7.6
Bokeh: 1.4.0
Holoviews: 1.14.3
Numpy: 1.19.5
Pandas: 1.0.1
Numba: 0.48.0
I have no problem running this example code:
...ANSWER
Answered 2021-May-25 at 21:34Your Datashader code works fine on my system:
Maybe you have some old versions, particularly of Numba?
QUESTION
Numba 0.53.1, Python 3.7.9, Windows 10 64bit
This doctest works fine:
...ANSWER
Answered 2021-Mar-28 at 18:57Please consider to rewrite your code another way, since it looks like your Numba code checks types of input data so block if yp.shape[1] == 3:
is checked in compilation stage, that is why it is not handled by try except
Please try the code below, it is identical to your code, but there is no order='F'
which does not want to work with Numba in any way.

I recently created a Console app which held the context of Pkcs11Interop library, along with HSM dll. It worked fine, however I needed to rewrite the code to Windows Service (I hosted it as gRPC service since it's .NET Core). After hosting WS, it ocurred that the slot list on factories.Pkcs11LibraryFactory.LoadPkcs11Library(factories, libraryPath, AppType.MultiThreaded).GetSlotList(SlotsType.WithOrWithoutTokenPresent).Find(slot => slot.SlotId == slotId) returns an empty list of slots, even though it returned list of 3 elements in console app.
...ANSWER
Answered 2021-Mar-28 at 16:47Pkcs11Interop returns slots received by calling C_GetSlotList
function of unmanaged PKCS#11 library. So if you get 0 slots then C_GetSlotList
returned 0 slots. You need to discuss this situation with the vendor of your PKCS#11 library who might know why their library does not see any slots.
QUESTION
Refering to this link C++\SQL ODBC: Get row from table I don't understand the docs and have tried many variations to get something to work but it just outputs complete jibberish. Basically, how can I get data from my Microsoft Access Database into my C++ program. I would eventually want to get the entire table stored as arrays or vectors, that being, lets say there are 5 fields in my table, I want to store (in 5 different arrays or vectors) all the contents to the corresponding fields. But for now, how can I just have something like a table called "Example Table" and within it it has 1 field called "Names" and the type is a string or "short text" as Access calls it. How can I then load that into an array of strings or char*'s to use for my GUI or other parts of the program? Here is my current code:
...ANSWER
Answered 2021-Mar-26 at 03:43You need to use SQLGetData, passing SQL_C_WCHAR type, for example, if your column is text. Here's example how to get values of the single text column and put them to vector:
QUESTION
I have created a python script that sets a filter on my google sheet. This filtering works as expected. I'm now interested in grabbing all the rows after setting this filter. However, when I do get api call, I'm getting all the rows.
I think I'm making a mistake in providing the range when I make get call. I provide range in this format Sheet1!A:J
. This range indicates all data in columns from A to J. However, I don't know how to provide only range corresponding to filtered data. I have seen one solution in google app script described in this post (https://sites.google.com/site/scriptsexamples/learn-by-example/google-sheets-api/filters#TOC-Get-filtered-rows). However, this is quite an inefficient solution. I don't want to run for loop on fetched data. I want to prevent fetching all data, and would rather prefer to fetch only the filtered data. Is that possible to do from python script?
I currently do it like this
...ANSWER
Answered 2021-Mar-24 at 02:54I believe your goal as follows.
From the following your replying,
I meant rows. So for example, I have selected only rows with TEXT_EQ value "Open", I want to fetch all the rows with value "Open" in certain column. Is this clear now or I need to elaborate more?
You want to retrieve the showing rows from the filtered sheet.
You are using googleapis for python, and you have already been able to get and put values for Google Spreadsheet using Sheets API.
From
I don't want to run for loop on fetched data.
, you want to achieve this without retrieving from all data by filtering with a script. You want to achieve this by only one API call.
In this case, I would like to propose to achieve your goal using the Query Language. When Query Language is used, the showing rows can be directly retrieved by one call. The sample script is as follows.
Sample script:Before you use this script, please set the Spreadsheet ID and sheet ID. And, this sample script uses creds
of service = build('sheets', 'v4', credentials=creds)
for retrieving the access token. So please include your authorization script.
QUESTION
I am trying to build a decentralized app that able to do show the block header like data hash, the previous hash of the block when a user submits a new transaction. However, It seems like the new version of Fabric Node SDK 2.2 removes the function queryblock.
I refer on the documentation at https://hyperledger.github.io/fabric-sdk-node/release-2.2/module-fabric-network.html and currently still looking for some workaround to show the block info of the user's transaction.
The ideal output that I wish to achieved is almost similar to what Hyperledger Explorer provide.The reference can be check at:
which show the information such as Number of Blocks, Data Hash, Previous Hash and other Block Information regarding the hash.
Some information that I able to gatherThere are some information like BlockEvent that have the name
blockData
in the interfaceBlockEvent
. However, I can't seem to find it whennpm install i fabric-network
.Since the user can query and check their hash with the ledger, a key or hash need to be returned to the user upon transaction success. Is there any API function for this? So far, I able to found there are
getTransactionId()
in the classTransaction
. But is this one that I need to use?
All of the reference since to deal with the old version of node SDK which is version 1.4.

I am using the following step in my azure-pipelines.yml
file:
ANSWER
Answered 2021-Mar-22 at 01:54In the Azure DevOps pipeline, it restore the package via service account instead of personal account. Check this doc: Package permissions in Azure Pipelines
To use packages from a feed in Azure Pipelines, the appropriate build identity must have permission to your feed. By default, the Project Collection Build Service is a Contributor. If you've changed your builds to run at project scope, you'll need to add the project-level build identity as a Reader or Contributor, as desired. The project-level build identity is named as follows:
[Project name] Build Service ([Organization name])
We could also do this via click the button Allow project-scoped builds

Answered 2021-Feb-18 at 14:10Numba doesn't understand the [:,None]
indexing for reshaping. Indeed, the latter is equivalent to [:,np.newaxis]
, as you may already know, and at the present time, np.newaxis
isn't a supported numpy features, which partly explains the error message. Here, you should just use vector.reshape((-1,1))
or np.expand_dims(vector,1))
instead, which should give:

I am trying to use apify to get a websites title but when I run the code I get error 403, anyone know a fix?
My Code:
...ANSWER
Answered 2021-Feb-15 at 12:45You're using run-sync-get-dataset-items
endpoint, which returns dataset (and only dataset, i.e. the items array, not the run object). Then you're trying to get the items, assuming you're providing defaultDatasetId
, which is undefined
in this case. In the end, you get an error. This would also explain why you see the items via the link.
Not sure why it's error 403, not 404, but I don't see the implementation of getItemsFromDataset(). Could you please check the above first?
