I have the following code:

```
import pymc as pm
from matplotlib import pyplot as plt
from pymc.Matplot import plot as mcplot
import numpy as np
from matplotlib import rc

res = [18.752, 12.450, 11.832]

v = pm.Uniform('v', 0, 20)

errors = pm.Uniform('errors', 0, 100, size = 3)

taus = 1/(errors ** 2)

mydist = pm.Normal('mydist', mu = v, tau = taus, value = res, observed = True)

model=pm.Model([mydist, errors, taus, v, res])
mcmc=pm.MCMC(model) # This is line 19 where the TypeError originates
mcmc.sample(20000,10000)

mcplot(mcmc.trace('mydist'))

```

For some reason it doesn't work, I get the 'TypeError: hasattr(): attribute name must be string' error, with the following trace:

```

```

How do I make it work and output "mydist"?

Edit: I posted a wrong trace at first by accident.

Edit2: It all must be because res doesn't have a name, because it's an array, but I don't know how to assign a name to it, so it'll make this work.
