Unable to run GridCal after installation

[anmold-07]

Hello,

I have successfully installed GridCal by installing anaconda, however, I'm unable to run it using this command: python -c "from GridCal.ExecuteGridCal import run; run()" on my windows 10. Whenever I run it I get the following error:

Could you please help me here? I'm not sure what I'm doing wrong.

Hi! I see some issues there:

• I see python 2.7, 32 bits....it must be 3.6 or newer for 64 bits
• Anaconda is cool for some things but they have done a really poor job supporting Qt, the graphic library...

So if you want to use GridCal as a library, I recomend removing Anaconda and installing python 3.7 from python.com, then install GridCal and all the libraries will be fine.

Otherwise just download the standalone GridCal that I provide. It comes with a ready to roll python distribution.

Read the installation part on the documentation if you need more details.

best regards, Santiago

Hello, Thanks for your quick response.

I'm unable to download the standalone setup file for windows. When I click the on the link provided it shows the following:

https://sanpv.files.wordpress.com/2019/05/gridcalsetup-1.zip might be temporarily down or it may have moved permanently to a new web address.

[anmold-07]

Also, how do I deal with this error? ModuleNotFoundError: No module named 'numba.pycc'

I have already installed the numba package but GridCal just stops here every time..

[SanPen]

About Numba, I have no clue, looks like a compiler thing... I am serving the setup with this link since wordpress is having issues with the installer: https://drive.google.com/file/d/1_ln73z0pKYcxw8TEYroWXTqK6ZYLY6hS/view?usp=drivesdk

please try

[SanPen]

Did you succeed?

[anmold-07]

Hello, I got the pip version up and running. Here's what I actually did: I uninstalled the 32 bit anaconda and installed the 64 bit version. Then, while running GridCal using pip, I was getting the THE NO MOULE FOUND NUMBA.PYCC error. I reinstalled the numba module and a couple of other libraries (upgraded Qt) and then the GUI worked perfectly. I didn't try out the link you posted because it is working just fine with pip as of now. In the future if it stops running for some reason, then I'll use the standalone version you posted. Thanks much for the help.

[SanPen]

I am glad it worked. Also, I appreciate all the feedback that you may provide. Best regards, Santiago

Hello, since I wanted to develop my own scripts using GridCal, I installed the standalone version. I wasn't able to use both spyder and GridCal to develop my own scripts due to an error already discussed in the issues section a few months ago. The GUI is working fine after the standalone download but I'm not sure how and where should I write my scripts. Could you please guide me here?

[SanPen]

Hi,

The way I develop is with an IDE called PyCharm. With it you can chose the python executable that you want go use, hence you would be able to choose the standalone python from GridCal. It takes a while to get used ro, but it is the best way to develop pythom IMHO.

This is the kind of error I am getting. Although I'm able to run the scripts (GridCal as a calculator is working), I'm not able to see any visualizations or graphs. What can be done now? I have set the python interpreter to standalone python.

Backend Qt5Agg is interactive backend. Turning interactive mode on.

I am using this configuration:

So with this it may be fixed.

Getting this error now

[SanPen]

Hi,

I see that you're trying to run scripts from the interactive python console. This is something I never do, since I write scripts and run them in normal operation mode.

However, if you install PyQt5, you will be able to use the ipython console. I do not ship PySide2 and PyQt5 with GridCal's python distro because in the normal operation this is not required, but you may always extend the distro with the packages you need of course.

You can manage the distribution packages directly from pycharm in the settings. See Project > Project interpreter, and there add packages with the + simbol

Best regards, Santiago

If I run it using a python file then I get the following error:

C:\GridCal\python\python.exe C:/Users/Anmol/.PyCharmCE2019.3/config/scratches/scratch.py Traceback (most recent call last): File "C:/Users/Anmol/.PyCharmCE2019.3/config/scratches/scratch.py", line 1, in from GridCal.Engine import File "C:\GridCal\python\lib\site-packages\GridCal\Engine__init__.py", line 18, in from GridCal.Engine.Devices import File "C:\GridCal\python\lib\site-packages\GridCal\Engine\Devices__init__.py", line 17, in from GridCal.Engine.Devices.branch import * File "C:\GridCal\python\lib\site-packages\GridCal\Engine\Devices\branch.py", line 29, in from GridCal.Engine.Devices.tower import Tower File "C:\GridCal\python\lib\site-packages\GridCal\Engine\Devices\tower.py", line 19, in from PySide2 import QtCore ImportError: DLL load failed: The specified procedure could not be found.

Process finished with exit code 1

I didn't exactly get what were you recommending. Should I uninstall PyQt5?

[SanPen]

nope, you should install it if you want to have iPython console. I have just done it and it worked for me on Windows10.

But my true recommendation is to drop the interactive console style of scripting and do it old-school by writing the script in a .py and running it.

Anyway, it is just a mater of preferences ;)

[anmold-07]

It's working well now.

Also, all the plots in the GUI like voltage magnitude, voltage angles, PV curves for continuation power flow; Can they also be plotted using scripting, for example, using pycharm without using the GUI ? If yes, could you please give a small example?

[SanPen]

Absolutelly,

In order to plot anything in gridcal you perform the simulation with the corresponding driver. In the case of voltage collapse:

    vc_options = VoltageCollapseOptions()
    # just for this test
    numeric_circuit = main_circuit.compile_snapshot()
    numeric_inputs = numeric_circuit.compute()
    Sbase = np.zeros(len(main_circuit.buses), dtype=complex)
    Vbase = np.zeros(len(main_circuit.buses), dtype=complex)
    for c in numeric_inputs:
        Sbase[c.original_bus_idx] = c.Sbus
        Vbase[c.original_bus_idx] = c.Vbus
    unitary_vector = -1 + 2 * np.random.random(len(main_circuit.buses))
    vc_inputs = VoltageCollapseInput(Sbase=Sbase,
                                     Vbase=Vbase,
                                     Starget=Sbase * (1 + unitary_vector))
    vc = VoltageCollapse(circuit=main_circuit, options=vc_options,
                         inputs=vc_inputs)
    vc.run()
    mdl = vc.results.mdl()
    mdl.plot()

[anmold-07]

Say I want to plot the voltage magnitudes and angles using a script after running a power flow on a power system. How shall I do that?

[SanPen]

Hi,

You can try this:

options = PowerFlowOptions(SolverType.NR, verbose=False)
power_flow = PowerFlowDriver(grid, options)
power_flow.run()

vm = np.abs(power_flow.results.voltage)
va = np.angle(power_flow.results.voltage)

And then plot ´vm´ and ´va´.
