Dear Junsen,
thank you for your message and for the info on the error.
This error probably comes from the code not being able to compile when you executed "python install.py". One of the reasons could be that a suitable C++ compiler was not found, yet there could be some other reason. If you paste here the output that you get when compiling the code, I can check what is the reason for the code not compiling properly.
Best regards, Jose
Hi Jose,
Thank you for your reply.
As you mentioned, I didn't install LAPACK on my Ubuntu, since I thought it is irrelevant if I only use the Julia version of dmrgpy
. However it turns out that this package is necessary.
For others who may encounter the same problem, I install it via
sudo apt-get install libblas-dev liblapack-dev
Now I can successfully run python test.py
using both the C++ and Julia backend and obtain the expected result.
Best, Junsen
Dear Jose
After installing your
dmrgpy
, and try to run the first example given inREADME
, I encounter the following error:In
test.py
, I simply copied your example:So why the error? Also, why "C++ backend not found", since I should have installed it using
python install.py
successfully. BTW,ITensor
works fine insidejulia
.Best, Junsen
