node.js - NodeJS Global, JSdom, Unit test -

this simple question: when use create dom jsdom: const dom = (html = '<!doctype html><body></body></html>') => { const domobject = new jsdom(html); const { window } = domobject; const { document } = (domobject).window; global.window = window; global.document = document; global.navigator = { useragent: 'jsdom', language: 'en' }; } module.exports = dom; and use on test such: import test 'tape'; import dom 'dom'; // create global dom dom(); and yet when test have document, window , navigator undefined in tests. it's strange, missing something? or making assumption on it's behavior. should approach differently? if how? thanks! and how it's done! http://airbnb.io/enzyme/docs/guides/jsdom.html worked beautifully, curious.

python - Converting a pyearth model -

i've create model pyearth , , i'd convert object format can translated other representations (for example c++ function). one approach parse str output of model.summary() : $ print(model.summary()) earth model ------------------------------------- basis function pruned coefficient ------------------------------------- (intercept) no 1.78778 h(x0-0.245279) no 1.73016 h(0.245279-x0) no -2.6705 h(x0-1.22149) no 0.31407 h(1.22149-x0) yes none ------------------------------------- mse: 12.2425, gcv: 12.2427, rsq: 0.3090, grsq: 0.3090 but lead float precision loss, , seems it'd fragile piece of logic. is there better way? looks there function pyearth.export.export_sympy() converts model sympy expression.

How do I convert an array of arrays into a multi-dimensional array in Python? -

i have numpy array (of length x) of arrays, of of same length (y), has type "object" , has dimension (x,). "convert" array of dimension (x, y) type of elements of member arrays ("float"). the way can see "manually" like [x x in my_array] is there better idiom accomplishing "conversion"? for example have like: array([array([ 0., 0., 1., 0., 0., 0., 0., 0., 0., 0.]), array([ 0., 1., 0., 0., 0., 0., 0., 0., 0., 0.]), array([ 0., 0., 1., 0., 0., 0., 0., 0., 0., 0.]), ..., array([ 0., 0., 0., 0., 0., 0., 0., 0., 0., 1.]), array([ 0., 0., 0., 0., 0., 0., 0., 1., 0., 0.]), array([ 0., 0., 0., 0., 0., 0., 0., 0., 0., 1.])], dtype=object) which has shape (x,) rather (x, 10). you can concatenate arrays on new axis. example: in [1]: a=np.array([1,2,3],dtype=object) ...: b=np.array([4,5,6],dtype=object) to make array of array
