Field is in deferred_load mode, so can't be accessed.

Hi there, I'm trying to plot my u and v fields. I understand that fieldset.show() is no longer supported so I am using plt.colormesh as per the NEMO tutorial but I'm getting the Error message listed in the title - I've tried googling my way around this but it just takes me back to the source code here. My code is below:

plt.pcolormesh(fieldset.U.grid.lon, fieldset.U.grid.lat, fieldset.U.data[0,0,:,:])
plt.show()

plt.pcolormesh(fieldset.V.grid.lon, fieldset.V.grid.lat, fieldset.U.data[0,0,:,:])
plt.show()

the error message reads as follows:

plt.show()

plt.pcolormesh(fieldset.V.grid.lon, fieldset.V.grid.lat, fieldset.U.data[0,0,:,:])
plt.show()

Ah, this is a good point. You will need to issue

fieldset.computeTimeChunk(0,1)
