MKL fatal error


#1

Excuse me. I have a question.

To upgrade nengo and nengo_gui by entering “pip install --upgrade nengo” and “pip install --upgrade nengo_gui” to terminal on ubuntu.
However, when I used nengo_gui on the browser of Firefox, an error occurred.

Screenshot1

On terminal,
"Starting nengo server at http://localhost:8080
Intel MKL FATAL ERROR: Cannot load libmkl_avx.so or libmkl_def.so."
was present.

I don’t know why.
What should I do? Please ask me. Thank you.


Nengo 2.6.0 released

That seems to be a problem with your numpy installation. You could try re-installing numpy using sudo pip install numpy --upgrade. If that doesn’t work, please let us know.

Hi @keiji-iwao, welcome to the forum!

This is an issue with NumPy; are you using conda? If so, according to this thread, you can fix this problem by reinstalling NumPy with:

conda install  -f  numpy

Let us know if that helps!

Thank you for your answer.
As Mr.Bekolay says, I fixed the problem by reinstalling NumPy.

Mr.Trevor and Mr.Aubin, thank you very much!!
