Singular Matrix Error Python

I have actually no concept what this is. If I create a particular plot initially in an application, it throws this error (edited to the essential part):

Traceback (most current contact last):

File “thescript.py”, line 2147, in AddPatchBarax.add_patch(patch)Data “C:Python25libsite-packagessibbap.orgaxes.py”, line 1471, in add_patchself._update_patch_limits§Data “C:Python25libsite-packagessibbap.orgaxes.py”, line 1492, in _update_patch_limitsself.transData.inverted())Data “C:Python25libsite-packagessibbap.org ranscreates.py”, line 1954, in invertedreturn CompositeGenericTransform(self._b.inverted(), self._a.inverted())Data “C:Python25libsite-packagessibbap.org ransdevelops.py”, line 1448, in invertedself._inverted = Affine2D(inv(mtx))Documents “C:Python25libsite-packages umpylinalglinalg.py”, line 445, in invreturn wrap(solve(a, identity(a.shape<0>, dtype=a.dtype)))Documents “C:Python25libsite-packages umpylinalglinalg.py”, line 328, in solveraise LinAlgError, ‘Singular matrix’numpy.linalg.linalg.LinAlgError: Singular matrix

But, the odd part is that if I create a completely different and also totally separate plot before this one, and then I attempt to plot this one, I execute not acquire this error and also this plot reflects fine. That provides no feeling to me. Or also, if I plot this “patch” on a plot with a few various other lines plotted, it additionally functions.

You watching: Singular matrix error python

Does anyone have any kind of idea what could be causing this? Thanks.


What can be happening is that the patch being added has no area. The logic it is failing in is in the autoscaling section, I think. This is why if there are various other things already in the plot or with other patches, then the code works fine because the borders aren’t the same.

Still though, I believed we had enough logic checks to prevent this kind of error. I view you are utilizing Python 2.5, which is older than what we currently support. Which version of sibbap.org are you using?

But, the odd component is that if I create a fully various and also completely sepaprice plot before this one, and also then I attempt to plot this one, I do not gain this error and also this plot mirrors fine. That makes no sense to me. Or also, if I plot this “patch” on a plot through a few other lines plotted, it likewise functions.

Does anyone have actually any kind of concept what can be bring about this? Thanks.

What can be happening is that the patch being added has actually no area. Thelogic it is failing in is in the autoscaling section, I think. This iswhy if tbelow are various other points already in the plot or through other patches,then the code functions fine bereason the boundaries aren"t similar.

See more: Goldman Sachs Elevator Straight To Hell Book Review, Straight To Hell Book Review

If it is helpful, once I print the worth of the patch, I obtain this:

patch is: Poly((735597, -12) ...)

What"s weird though, is that the other plot I"m talking around is a*different* plot completely (various canvas instance), and can be closedfirst and also still "allow" the patch plot to be shown without errors.

Still though, I thought we had sufficient logic checks to prevent this sort oferror. I view you are using Python 2.5, which is older than what wecurrently support. Which version of sibbap.org are you using?

I"m utilizing sibbap.org 1.1.0. I might try upgrading.

Ben and also others,

OK, I tried upgrading to Python 2.6 and sibbap.org 1.4.2. The difficulty withthe singular matrix goes away! But...

...But now I have no patch shown on the plot. This is the function I amutilizing currently to add a patch (editing and enhancing to just keep the MPL relevantstuff)...maybe this is no much longer an excellent way?:

def AddPatch(self,): ax = self.subplot verts = < (start, y-scaling_value), # left, bottom (start, y+scaling_value), # left, optimal (soptimal, y+scaling_value), # best, optimal (soptimal, y-scaling_value), # ideal, bottom (0., 0.), # ignored > codes =

x = # x selection of box (in datacoordinates) elevation = 12 # of box in tool coords (pixels) route = mroute.Path(<, -height>, , -height>, , height>, , height>, , -height>>)

#USING THE NEW TRANSFORMS fixed_pt_trans = FixedPointOffsetTransform(ax.transDocuments,(0, y)) xdata_yaddressed =mtrans.blended_transform_factory(ax.transData, fixed_pt_trans)

patch = patches.PathPatch(route, transform=xdata_yaddressed,facecolor=shade,alpha=0.4, lw=1, edgecolor="grey")
