I just recently reinstalled fenics in wsl using conda

```
conda create -n fenics -c conda-forge fenics
```

And I am trying to run a sample code in fenics

```
from __future__ import print_function
# from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
%matplotlib inline
from fenics import *
# from dolfin import *
# from mshr import *
from ufl import nabla_div
# Scaled Variables
L = 1
W = 0.2
mu = 1
rho = 1
delta = W/L
gamma = 0.4*delta**2
beta = 1.25
lambda_ = beta
g = gamma
# Create Mesh and define function space
mesh = BoxMesh(Point(0,0,0), Point(L,W,W), 10, 3, 3)
V = VectorFunctionSpace(mesh, 'P', 1)
# Define Boundary Conditions
tol = 1e-14
def clamped_boundary(x, on_boundary):
return on_boundary and x[0] < tol
bc = DirichletBC(V, Constant((0,0,0)), clamped_boundary)
# Define Strain and Stress
def epsilon(u):
return 0.5 * (nabla_grad(u) + nabla_grad(u).T)
def sigma(u):
return lambda_*nabla_div(u)*Identity(d) + 2*mu*epsilon(u)
# Define variational problem
u = TrialFunction(V)
d = u.geometric_dimension() # space dimension
v = TestFunction(V)
f = Constant((0,0,-rho*g))
T = Constant((0,0,0))
a = inner(sigma(u), epsilon(v))*dx
L = dot(f, v)*dx + dot(T, v)*ds
# Compute Solution
u = Function(V)
solve(a == L, u, bc)
# Plot Solution
plot(u)
```

I encountered this error,

```

```

I think in the plotting.py file the `ax.set_aspect("equal")`

instead of “auto”.

Can you tell me how to bypass this error?
