TypingError appearing on Python lectures on stochastic growth

[ssingleton]

Here is the head of the error on Stochastic Growth 1:
TypingError Traceback (most recent call last) <ipython-input-10-597809653131> in <module> 3 4 v_init = v_star(grid, α, β, μ) # Start at the solution ----> 5 v = T(v_init) # Apply the Bellman operator once 6 7 fig, ax = plt.subplots(figsize=(9, 5))

Here is the head of the error on Stochastic Growth 2:
TypingError Traceback (most recent call last) <ipython-input-9-7c0cb6c2538d> in <module> 7 for i in range(sim_length): 8 σ = K(σ) # Time iteration ----> 9 v = T(v) # Value function iteration 10 11 # Calculate difference with actual solution

There are more errors, but I didn't want to overwhelm this page.

Thanks @ssingleton, much appreciated!

Numba has changed and broken our jitted scalar optimizer. See #495. This is flowing on to our lectures.

@mmcky has put together a temporary fix but I guess it's not published yet?

hey @ssingleton thanks for the report.

The local fix if you would like to run those lectures is to upgrade numba

conda install numba=0.44.1

@jstac the update to 0.44.1 hasn't been pushed yet due to the introduction of the other failure for the int_ type checking issue.

[mmcky]

the latest release of anaconda has numba=0.45.1 so this should no longer be an issue.

thanks @ssingleton for reporting this. Please let us know if you spot any other errors.
