java - Maven project compiles but there are missing imports in the workspace -

-

i'm using eclipse kepler m2e plugin , want modify maven project , compile it. first converted maven project configure -> convert maven project, there still many missing imports. when use run as... -> maven install project compiles.

how can fix missing imports?

tell m2e update project: context menu of project / maven / update project...

m2e read pom again , update classpath , build project again.

make sure have in .classpath file:

<classpathentry kind="con" path="org.eclipse.m2e.maven2_classpath_container">     <attributes>         <attribute name="maven.pomderived" value="true"/>     </attributes> </classpathentry>

note: actual syntax might different depending on m2e version use.

another common pitfall scope provided:

provided
compile, indicates expect jdk or container provide dependency @ runtime. example, when building web application java enterprise edition, set dependency on servlet api , related java ee apis scope provided because web container provides classes. scope available on compilation , test classpath, , not transitive.

note last part: not transitive

this means depend on pom says "i need x:y:z, scope provided". project see dependency won't on classpath @ all.

to fix this, copy dependency project same scope (provided).

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
