python - IndexError : index out of bounds -


i have implemented multinomialnb message. please me solve it. here code : 

kf = kfold(len(x), n_folds=2, shuffle=true, random_state=9999)  model_train_index = []  model_test_index = []  model = 0    k, (index_train, index_test) in enumerate(kf):      x_train, x_test, y_train, y_test = x.ix[index_train,:], x.ix[index_test,:],y[index_train], y[index_test]      clf = multinomialnb(alpha=0.1).fit(x_train, y_train)      score = clf.score(x_test, y_test)      f1score = f1_score(y_test, clf.predict(x_test))      precision = precision_score(y_test, clf.predict(x_test))      recall = recall_score(y_test, clf.predict(x_test))      print('model %d has accuracy %f | f1score: %f | precision: %f | recall : %f'%(k,score, f1score, precision, recall))      model_train_index.append(index_train)      model_test_index.append(index_test)      model+=1

and result : 

indexerror                                traceback (most recent call last)  <ipython-input-3-df0b24edb687> in <module>()        5         6 k, (index_train, index_test) in enumerate(kf):  ----> 7     x_train, x_test, y_train, y_test = x.ix[index_train,:], x.ix[index_test,:],y[index_train], y[index_test]        8     clf = multinomialnb(alpha=0.1).fit(x_train, y_train)        9     score = clf.score(x_test, y_test)    indexerror: index 100 out of bounds axis 0 size 100

python uses 0 based indexing if zeroth dimension of x.ix[index_train,:] or y[index_train] 100, maximum value of index_train valid 99. likewise index_test.

something in

kf = kfold(len(x), n_folds=2, shuffle=true, random_state=9999)

is causing 1 of indices large 1 of arrays @ time enumerate(kf).

amazon web services - S3 Pre-signed POST validate file type? -

i know it's possible put limit on file size content-length-range header. possible validate file type? https://docs.aws.amazon.com/amazons3/latest/dev/httppostforms.html#policyconditions i see there content-type header, if set say, audio/mp3 allow mp3 files , return error if file not mp3? i found previous question answers mention validating file size: s3 direct upload restricting file size , type you can specify content-type @ post request. you can specify @ signature, post must done content-type: { "expiration": "2007-12-01t12:00:00.000z", "conditions": [ {"acl": "public-read" }, {"bucket": "johnsmith" }, {"content-type: "audio/mp3"} ] } creating html form (using aws signature version 4) edit: @ previous question found, checking content-type.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
