Code using tfjs-node:
const model = await tf.node.loadSavedModel(modelPath);
const data = fs.readFileSync(imgPath);
const tfimage = tf.node.decodeImage(data, 3);
const expanded = tfimage.expandDims(0);
const result = model.predict(expanded);
console.log(result);
for (r of result) {
console.log(r.dataSync());
}
Output:

How do I read the predict() response for object detection? I was expecting a dictionary with num_detections, detection_boxes, detection_classes, etc. as described here.
I also tried using tf.execute(), but it throws me the following error: UnhandledPromiseRejectionWarning: Error: execute() of TFSavedModel is not supported yet.
I'm using efficientdet/d0 downloaded from here.
When you download the tensor using dataSync() it just keeps the value. If you wanted the object with a description of each of the results without the tensors you would just have to console.log(result). Then you expand the result from your log in the browsers console it should return something like this:
Tensor {
"dataId": Object {},
"dtype": "float32",
"id": 160213,
"isDisposedInternal": false,
"kept": false,
"rankType": "2",
"scopeId": 365032,
"shape": Array [
1,
3,
],
"size": 3,
"strides": Array [
3,
],
}
The output of your console.log(result) contains 8 tensors within it which shows that it is correct. You are looping over each of the results and each of the outputs should follow this format :
['num_detections', 'detection_boxes', 'detection_classes', 'detection_scores', 'raw_detection_boxes', 'raw_detection_scores, 'detection_anchor_indices', 'detection_multiclass_scores']
When trying to switch a schedule trigger from a monthly by-weekday schedule to a by-date schedule, I get an error saying 'day_of_week' nor 'which_occurrence' can be specified when creating a monthly date-based trigger.
However, I am not using either of these properties in the new configuration.
Error: Neither 'day_of_week' nor 'which_occurrence' can be specified when creating a monthly date-based trigger

This appears to be a bug in the scheduled_task module. When I remove the existing task and run the code again, it applies without issue.
I'm generating a dynamic update query based on a list of provided objects for postgres. This is what my query looks like:
update loan_item_assignment as t set id = c.id, dateselectionid = c.dateselectionid, loanitemid = c.loanitemid, active = c.active, type = c.type from (values ( $1, $2, $3, $4, $5 ), ( $6, $7, $8, $9, $10 ), ( $11, $12, $13, $14, $15 ), ( $16, $17, $18, $19, $20 ), ( $21, $22, $23, $24, $25 ), ( $26, $27, $28, $29, $30 ), ( $31, $32, $33, $34, $35 ), ( $36, $37, $38, $39, $40 ) ) as c( id, dateselectionid, loanitemid, active, type ) where c.id = t.id returning *
And here's the values list I'm giving it:
[ 7,
35,
3,
true,
'normal',
8,
35,
4,
true,
'normal',
1,
35,
6,
true,
'normal',
2,
35,
7,
true,
'normal',
3,
35,
8,
true,
'normal',
5,
35,
10,
true,
'normal',
4,
35,
11,
true,
'normal',
6,
35,
12,
true,
'normal' ]
As far as I can tell, the values match up correctly. This is the error I'm seeing:
{ [error: operator does not exist: text = integer]
name: 'error',
length: 195,
severity: 'ERROR',
code: '42883',
detail: undefined,
hint: 'No operator matches the given name and argument type(s). You might need to add explicit type casts.',
position: '448',
internalPosition: undefined,
internalQuery: undefined,
where: undefined,
schema: undefined,
table: undefined,
column: undefined,
dataType: undefined,
constraint: undefined,
file: 'parse_oper.c',
line: '726',
routine: 'op_error' }
And this is the code that's ultimately running the query:
var performQuery = function(text, values, cb) {
pg.connect(connectionString, function(err, client, done) {
client.query(text, values, function(err, result) {
done();
if (!result) {
console.log(err);
cb([], err);
} else {
cb(result.rows, err);
}
})
});
}
And here is the table definition:
Table "public.loan_item_assignment"
Column | Type | Modifiers | Storage | Stats target | Description
-----------------+---------+-------------------------------------------------------------------+----------+--------------+-------------
id | integer | not null default nextval('loan_item_assignment_id_seq'::regclass) | plain | |
dateselectionid | integer | | plain | |
loanitemid | integer | | plain | |
active | boolean | | plain | |
type | text | | extended | |
Indexes:
"loan_item_assignment_pkey" PRIMARY KEY, btree (id)
Foreign-key constraints:
"loan_item_assignment_dateselectionid_fkey" FOREIGN KEY (dateselectionid) REFERENCES date_selection(id)
"loan_item_assignment_loanitemid_fkey" FOREIGN KEY (loanitemid) REFERENCES loan_item(id)
Vitaly-t's comment on my answer is the solution - to use the pg-promise library to generate the query, and specifically method helpers.update for generating multi-row update queries, as shown in PostgreSQL multi-row updates in Node.js.
I am trying to pass an array of arrays from routes to view page. My data that I am trying to pass is :
[
[10, 10],
[20, 50],
[30, 120],
[40, 80],
[50, 90],
[60, 50],
[70, 70],
[80, 90],
[90, 150],
[100, 50],
[110, 40],
[120, 70],
[130, 20],
[140, 40],
[200, 30]
]
I am getting it in below format:
["10,10,20,50,30,120,40,80,50,90,60,50,70,70,80,90,90,150,100,50,110,40,120,70,130,20,140,40,200,30"]
but I need it in the same format I am sending.
My index.js(routes file) is:
router.get('/', function(req, res, next) {
var dataset = [
[10, 10],
[20, 50],
[30, 120],
[40, 80],
[50, 90],
[60, 50],
[70, 70],
[80, 90],
[90, 150],
[100, 50],
[110, 40],
[120, 70],
[130, 20],
[140, 40],
[200, 30]
];
console.log(dataset);
res.render('index',{"data" : [dataset]});
});
module.exports = router;
and in my view file, I am trying to get it like:
<div class="hold_data" data-info={{data}}></div>
Please suggest if anyone knows how this can be achieved. Thanks in advance :)
Try JSON.stringify as below -
res.render('index',{"data" : JSON.stringify(dataset)});
Hope this helps.
I try to implement a Line Chart with string on xAxie and vAxie.

it is ok I found a way to do it with direction: -1 in vaxis option.

Thank you
