Ndd library can't run . No 'ndd.fnsb' file

[YutaoChen0512]

Hello, the test_basic.py file in the test folder runs error.
ModuleNotFoundError: No module named 'ndd.fnsb'
Calculating the entropy using ndd alone will also report an error.
ModuleNotFoundError: No module named 'ndd.fnsb'

I don't know how to solve this problem, I hope I can get your help. Thank you for answering my question.

Hi,
this is small script that collects some info on your system:
https://gist.github.com/simomarsili/dcadc9a4e8ceff9043bcc56c540479cf

Can you run it and paste here the output?
Thank you

No problem. This is the script:

print(

Am I lacking the conditions for running the NDD library?

Am I lacking the conditions for running the NDD library?

This looks like a windows-related issue (the package is not tested under windows). I think it can be solved.

• In the package installation dir:
  C:\SSD\python3.6.7\lib\site-packages\ndd
  check if you have a .libs directory.
• In the .libs directory, you should find a .dll file.
  Copy this file to the ndd directory (the installation dir).
• Finally, try to import ndd (python -c "import ndd") and paste here any error message

[YutaoChen0512]

Because I can't use pip to install ndd.
Ndd directory only you upload to github program, did not find .dlls directory and .dll files.
The reasons for the error are as follows:

ERROR: Command errored out with exit status 1: 'C:\SSD\python3.6.7\python.exe' -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'C:\Users\cyt\AppData\Local\Temp\pycharm-packaging\ndd\setup.py'"'"'; file='"'"'C:\Users\cyt\AppData\Local\Temp\pycharm-packaging\ndd\setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(file);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, file, '"'"'exec'"'"'))' install --record 'C:\Users\cyt\AppData\Local\Temp\pip-record-t8bcckrr\install-record.txt' --single-version-externally-managed --compile Check the logs for full command output.

Please download the python wheel ndd-1.4.1-cp37-cp37m-win_amd64.whl from this repo:

https://github.com/simomarsili/ndd-wheels

(direct link to the file)

Install it using pip:

pip install ndd-1.4.1-cp37-cp37m-win_amd64.whl

the wheel contains the ndd package with compiled extensions for Windows.
This should work. Let me know.
Bye

Sorry, I have not been able to respond to your information in time because of some things.
I have installed the new ndd library.But still have previous problems.
The contents of python -c "import ndd" are as follows：

ModuleNotFoundError: No module named 'ndd.fnsb'

[simomarsili]

try to update your numpy version:
pip install -U numpy
