I am looking to perform raw transaction between t-address and z-addresses of zcash
I have tried the following things
when i use createrawtransaction it is throwing "invalid zcash address"
error
~/zcash$ ./src/zcash-cli createrawtransaction
'[{"txid":"f7e04b684ee10c3c8e7aacdcd11454e7f21d91c5a8b27ae6cbbbca93efa57ddd","vout":0}]'
'{"ztJTQ72v68ZddM4vmJg77K1mdBXHWQPS8GXN4Yb7A8e48JUo3tNzLgej1yqFPFeNkVUL1CMeg62qHMr7joaYK35A86neMNM":7,"tmNHNUV56LiEyb8cSrrAgupHXnrxhbN1H6v":2.9999}'
error code: -5 error message: Invalid Zcash address:

In the RPC call above :
the address format you are using ztJTQ72v68ZddM4vmJg77K1mdBXHWQPS8GXN4Yb7A8e48JUo3tNzLgej1yqFPFeNkVUL1CMeg62qHMr7joaYK35A86neMNM is not in the acceptable format, please use an acceptable encoded format public address.
Your second parameter tmNHNUV56LiEyb8cSrrAgupHXnrxhbN1H6v is the correct format used while calling this RPC method.
Rest all looks good.

I'm using OpenCVinside one of my projects (iOS app). I'm trying to use cvMatchTemplate (Link : Documentation ) . For some reason I'm getting this error :
OpenCV Error: Bad argument (Unknown array type) in cvarrToMat, file /Volumes/build-storage/build/master_iOS-mac/opencv/modules/core/src/matrix.cpp, line 943
libc++abi.dylib: terminating with uncaught exception of type cv::Exception: /Volumes/build-storage/build/master_iOS-mac/opencv/modules/core/src/matrix.cpp:943: error: (-5) Unknown array type in function cvarrToMat
Running this code:
cv::Mat mOriginal, mTemp,res;
UIImageToMat(original, mOriginal);
UIImageToMat(temp, mTemp);
// Crashing at this line
cvMatchTemplate(&mOriginal, &mTemp, &res, CV_TM_CCOEFF_NORMED);
Any help would be greatly appreciated. Thank you.
#Miki too humble to post his answer :)
Don't use obsolete C api. Use cv::matchTemplate
Working code:
cvMatchTemplate(mOriginal, mTemp, res, CV_TM_CCOEFF_NORMED);
We are using Bsafe cpp code in an application to verify the signature, but it is raising back with error code 540 while calling B_VerifyFinal.
Is it possible to know what this error code corresponds to? and how we will find all the error messages for bsafe error codes.
Thanks in advance.
I use Pandas 0.12.0 and definded a read csv function as follows:
df=pandas.DataFrame.from_csv(inputpfad,index_col=2, parse_dates=[0,5],
infer_datetime_format=True)
However, I got as error message:
TypeError: from_csv() got an unexpected keyword argument 'infer_datetime_format'
I set it to true to speed up the parsing. Might it not be supported
in my Pandas-version?
