Setting a broken git branch to a detached head -

-

after power loss during commit, 1 of branches in git repository got corrupted. did git fsck --full , deleted empty object files until fsck gave me:

checking object directories: 100% (256/256), done. checking objects: 100% (894584/894584), done. error: refs/heads/git-annex not point valid object! checking connectivity: 862549, done.

i used git fsck --lost-found find last dangling commit on git-annex branch. checked out.

i want replacement git-annex head. tried git checkout -b git-annex got branch exists. tried git branch -d git-annex got error: couldn't commit object 'refs/heads/git-annex'.

how can rid of broken git-annex branch in order set commit want? have tried removing .git/refs/heads/git-annex doesn't work. thanks.

this works me (after "cheating" insert broken branch, , seeing same error when trying delete it):

git branch -f broked head  # or other valid point git branch -d broked

the second command gripes deletes broken ref .git/packed-refs (which assume must if removing .git/refs/heads/git-annex unhelpful). (but branch name "git-annex" makes me wonder if you're using git-annex, in, thing stores large files outside repo. have not used myself , not sure if changes anything.)

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...
