ModuleNotFoundError: No module named 'lascar.tools'

#1

Dear all,
To use lascar module, in my jupyter notebook, I typed

git clone https://github.com/Ledger-Donjon/lascar.git
cd lascar

  Then I found that the execution of the following line

python3 setup.py develop

would take too much time; thus I type this line in my command line terminal.
Then I restart the kernel; I execute the following lines in jupyter notebook,

from lascar import *
from lascar.tools.aes import sbox, inv_sbox

I got an error message as:
ModuleNotFoundError: No module named ‘lascar.tools’

Why?

If you remove the from lascar.tools.aes import sbox, inv_sbox line, does the command succeed?

Hey Nafisa,
The way I fixed this problem is as follows:
1. Go to the folder WPy64-3740, click WinPython Command Prompt.
2. Follow the steps, first type

1 pip3 install lascar

Once the installation completes, type

2 cd lascar
3 python setup.py develop

Now, reset the jupyter kernel. Hope this would help you.
