Fail to Repeat Example 1

[yxu148]

Hi,

I copied and pasted all codes from

example_1_pyloric_network.ipynb

and ran in Spyder with Python3.7.

I didn't run the plotting codes to test if the codes work. There is an error, and the error message says

Cannot find Microsoft Visual Studio, You can try to set the path to vcvarsall.bat via the codegen.cpp.msvc_vars_location preference explicitly.

Should I use Visual Studio instead?

Hi @yxu148 . For efficiency reasons, the example switches on code generation for C++ with the line:

set_device('cpp_standalone', build_on_run=False)

For this to work, you need to have a working C++ compiler installed as explained here: https://brian2.readthedocs.io/en/stable/introduction/install.html#requirements-for-c-code-generation

Alternatively, you can remove the set_device(...) line – the simulation will run, but just not as fast.
