TypeError: FigureBase.gca() got an unexpected keyword argument 'projection'

Question

axes1 = fig.gca(projection = '3d')

1 axes1 = fig.add_axes(Axes3D(fig))
2 axes1 = fig.gca(projection=Axes3D.name)
3 axes1 = fig.add_subplot(projection='3d')

These are all the solutions i found during google, the first is the origional type of code, but was unusable after matplotlib 3.4 but the other 3 solution works differently with the first one

it's what I expected:

it's the 1th:

Answer 1

This error happens due to Matplotlib update.

You can use

axes1 = fig.add_subplot(projection = '3d')

instead of

axes1 = fig.gca(projection = '3d')
