我尝试在github上使用一段代码，整个项目https://github.com/rtshadow/biometrics 我用了
python thining.py image.gif --save
但它有一个错误：
Traceback (most recent call last):
File "thining.py", line 77, in <module>
make_thin(im)
File "thining.py", line 59, in make_thin
utils.load_pixels(im, loaded)
File "---/Github/biometrics/utils.py", line 111, in load_pixels
im_load[i, j] = pixels[i][j]
SystemError: new style getargs format but argument is not a tuple
utiles.py的相应部分在这里：
def load_pixels(im, pixels):
(x, y) = im.size
im_load = im.load()
for i in range(0, x):
for j in range(0, y):
im_load[i, j] = pixels[i][j] // line 111
我不知道如何解决它。谢谢你的帮助。

检查您的Python版本：module LED_breath (led, tmr_clk);
output reg led;
input tmr_clk;
reg [7:0] cnt;
reg [6:0] pwm_cnt;
reg [6:0] pwm_val;
reg [2:0] pat_cnt;
reg [9:0] delay_cnt;
reg [6:0] cur_pat;
reg [6:0] nxt_pat;
parameter pattern = {7'h00, 7'h00, 7'h00, 7'h00, 7'h00, 7'h00, 7'h00, 7'h00};
always @(posedge tmr_clk)
begin
pwm_cnt = cnt[7] ? ~cnt[6:0] : cnt[6:0]; //Generate triangle wave
if(pwm_cnt > pwm_val) //Generate pwm
led <= 1'b0;
if(pwm_cnt < pwm_val)
led <= 1'b1;
cnt = cnt + 1;
end
always @(posedge tmr_clk) //breathing pattern
begin
if(!delay_cnt) //Add delay
begin
cur_pat <= ((pattern >> (7*pat_cnt)) & 7'b1111111); //Find correct pattern No. from parameter list
if((pat_cnt+1) == 8) //Check for last pattern - overflow, set to 0
nxt_pat <= (pattern & 7'b1111111);
else
nxt_pat <= ((pattern >> (7*(pat_cnt+1))) & 7'b1111111);
if(pwm_val == nxt_pat) //If pwm is at max or min increment count to get next pattern
pat_cnt <= pat_cnt + 1;
if(cur_pat <= nxt_pat) //Current pattern < next pattern, count up
pwm_val <= pwm_val + 1;
if(cur_pat >= nxt_pat) //Current pattern < next pattern, count down
pwm_val <= pwm_val - 1;
end
delay_cnt <= delay_cnt + 1;
end
endmodule
module top (led_0, led_1, led_2, led_3);
output led_0;
output led_1;
output led_2;
output led_3;
defparam I1.TIMER_DIV = "128";
OSCTIMER I1 (.DYNOSCDIS(1'b0), .TIMERRES(1'b0), .OSCOUT(osc_clk), .TIMEROUT(tmr_clk));
LED_breath #(.pattern({7'h20, 7'h70, 7'h50, 7'h70, 7'h40, 7'h10, 7'h60, 7'h10})) led_A(
.led (led_0),
.tmr_clk (tmr_clk)
);
LED_breath #(.pattern({7'h70, 7'h10, 7'h30, 7'h20, 7'h60, 7'h40, 7'h70, 7'h10})) led_B(
.led (led_1),
.tmr_clk (tmr_clk)
);
LED_breath #(.pattern({7'h10, 7'h30, 7'h10, 7'h18, 7'h40, 7'h50, 7'h30, 7'h60})) led_C(
.led (led_2),
.tmr_clk (tmr_clk)
);
LED_breath #(.pattern({7'h50, 7'h70, 7'h40, 7'h50, 7'h40, 7'h70, 7'h60, 7'h70})) led_D(
.led (led_3),
.tmr_clk (tmr_clk)
);
endmodule
。它似乎适用于2.7.6，但不是2.7.10。 （见原帖的评论。）
