php - Why am I getting this error -

-

the path of filename correct, reason i'm getting error below when run script .. phpinfo shows me imagick installed ...and downloaded ghostscript i'm not sure if detects .. did downloading computer .. there i'm missing ? i'm confused on how ghostscript work php

fatal error: uncaught exception 'imagickexception' message 'can not process empty imagick object' in c:\xampp\htdocs\tms\test_php.php:7 stack trace: #0 c:\xampp\htdocs\tms\test_php.php(7): imagick->setimageresolution(1250, 1250) #1 {main} thrown in c:\xampp\htdocs\tms\test_php.php on line 7

php code:

    //echo phpinfo();     $filename = dirname(__file__).'\_media\4055-beckman-lead-app\client\fpo.pdf';     echo $filename;     $im = new imagick( $filename, 0777);      $im->setimageresolution(1250,1250);     $im->setimagecolorspace(255);     $im->setcompression(imagick::compression_jpeg);     $im->setcompressionquality(100);     $im->setimageformat('jpeg');      $im->writeimage('thumb.jpg');     $im->clear();     $im->destroy();

it appears though constructor imagick class should have 1 parameter passed it, passing 2 ($filename, 0777).

replace

$im = new imagick( $filename, 0777);

with

$im = new imagick($filename);

(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...
