enter image description here 我收到以下错误,无法识别getContext()。
答案 0 :(得分:0)
你刚才写道:
train_set =[]
lbl_train=[]
for cl_ in range(50):
for ex_ in range(15):
cl = str("%02d" % (cl_+1,))
ex = str("%02d" % (ex_+1,))
img = Image.open('cropped_faces/'+'s'+str(cl)+'_'+str(ex)+'.jpg').convert('L')
wpercent = (basewidth / float(img.size[0]))
hsize = int((float(img.size[1]) * float(wpercent)))
img = img.resize((basewidth, hsize), Image.ANTIALIAS)
lbl_train.append(cl)
mat = numpy.asarray(img,dtype=numpy.float)
train_set.append(mat.reshape(len(mat),len(mat[0])))
print(numpy.asarray(train_set).shape)
print(numpy.asarray(train_set[0]).shape)
而不是:
canavas = document.getElementById('gameCanvas');
错误的名字。在提出问题之前尝试搜索一下
