I have successfully built and trained an audioCaffe demo, but the demo doesn't save the network.
I have found documentation for saving the network in Python in MatLab, but I can't find any documentation on C++.
I would think there would be a similar function like net.save("file.caffemodel") but I tried that and it didn't work.
In the train function in caffe.cpp I tried this:
if (FLAGS_snapshot.size()) {
LOG(INFO) << "Resuming from " << FLAGS_snapshot;
solver.Solve(FLAGS_snapshot);
} else if (FLAGS_weights.size()) {
LOG(INFO) << "Finetuning from " << FLAGS_weights;
solver.net()->CopyTrainedLayersFrom(FLAGS_weights);
solver.Solve();
} else {
solver.Solve();
}
solver.save("file.caffemodel")
But I got a no method exists error
Any ideas?
Please try this...
caffe::NetParameter net_param;
net_->ToProto(&net_param);
caffe::WriteProtoToBinaryFile(net_param, caffe_model_path);
You should look at Snapshot() and SnapshotToBinaryProto() - src/caffe/solver.cpp.
Caller code is in Solver::Step:
// Save a snapshot if needed.
if ((param_.snapshot()
&& iter_ % param_.snapshot() == 0
&& Caffe::root_solver()) ||
(request == SolverAction::SNAPSHOT)) {
Snapshot();
}

I have written an IoT Edge C++ module that is sending the event output using the following function call:
bool IoTEdgeClient::sendMessageAsync(std::string message)
{
bool retVal = false;
LOGGER_TRACE(IOT_CONNECTION_LOG, className + "::sendMessageAsync(...) START");
LOGGER_DEBUG(IOT_CONNECTION_LOG, className + "::sendMessageAsync(...) message : " << message);
Poco::Mutex::ScopedLock lock(_accessMutex);
MESSAGE_INSTANCE *messageInstance = CreateMessageInstance(message);
IOTHUB_CLIENT_RESULT clientResult = IoTHubModuleClient_LL_SendEventToOutputAsync(_iotHubModuleClientHandle, messageInstance->messageHandle, "output1", SendConfirmationCallback, messageInstance);
if (clientResult != IOTHUB_CLIENT_OK)
{
LOGGER_ERROR(IOT_CONNECTION_LOG, className + "::sendMessageAsync(...) ERROR : " << message << " Message id: " << messageInstance->messageTrackingId);
retVal = false;
}
else
{
retVal = true;
}
LOGGER_TRACE(IOT_CONNECTION_LOG, className + "::sendMessageAsync(...) END");
return retVal;
}
The result of the function call IoTHubModuleClient_LL_SendEventToOutputAsync is always coming as IOTHUB_CLIENT_OK. My module name is MicroServer and the route configured is:
FROM /messages/modules/MicroServer/outputs/output1 INTO $upstream
I do not see the SendConfirmationCallback function being called. Also, I do not see any device to cloud message appearing in the IoT hub. Any ideas why this is happening and how to fix it?
It turned out that I need to call this function atleast a couple of times per second
IoTHubModuleClient_LL_DoWork(_iotHubModuleClientHandle);
which I was not doing. As a result the code was not working properly. Once I started doing it. The code just worked.
I've connected my C++ project to MySQL and successfully created a session. I was able to create a Schema. My issue is that when I try to run simple arbitrary queries like USE testSchema SHOW tables; using the MySQL/C++ api, I run into SQL syntax errors. When I run the function directly in the MySQL shell, the query runs perfectly fine.
Here is the full code
const char* url = (argc > 1 ? argv[1] : "mysqlx://pct#127.0.0.1");
cout << "Creating session on " << url << " ..." << endl;
Session sess(url);
{
cout << "Connected!" << endl;
// Create the Schema "testSchema"; This code creates a schema without issue
cout << "Creating Schema..." << endl;
sess.dropSchema("testSchema");
Schema mySchema = sess.createSchema("testSchema");
cout << "Schema Created!" << endl;
// Create the Table "testTable"; This code runs like normal, but the schema doesn't show
cout << "Creating Table with..." << endl;
SqlStatement sqlcomm = sess.sql("USE testSchema SHOW tables;");
sqlcomm.execute();
}
Here is the console output:
Creating session on mysqlx://pct#127.0.0.1 ...
Connected!
Creating Schema...
Schema Created!
Creating Table with...
MYSQL ERROR: CDK Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SHOW tables' at line 1
The error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SHOW tables' at line 1 is a MySQL error that means I have a syntax error in the query, but when I take a closer look at a query, I see there is nothing wrong with it.
I've copied and pasted the code directly from the cpp file into the mysql shell and it runs perfectly. This tells me that something is up with the formatting of how I'm entering the query in the sql() function. But the documentation for the sql() function is really terse and.
Here is the reference to the sql() function: https://dev.mysql.com/doc/dev/connector-cpp/8.0/class_session.html#a2e625b5223acd2a3cbc5c02d653a1426
Can someone please give me some insight on where I'm going wrong? Also here here is the full cpp code for more context:https://pastebin.com/3kQY8THC

You can do it in two steps:
sess.sql("USE testSchema").execute();
SqlStatement sqlcomm = sess.sql("SHOW tables");
SqlResult res = sqlcomm.execute();
for(auto row : res)
{
std::cout << row.get(0).get<std::string>() << std::endl;
}
Also, you can use the Schema::getTables():
for(auto table : mySchema.getTables())
{
std::cout << table.getName() << std::endl;
}
Keep in mind that the Schema::getTables() doesn't show the Collections created by Schema::createCollection(). There is also a Schema::getCollections():
for(auto collection : mySchema.getCollections())
{
std::cout << collection.getName() << std::endl;
}
I'm attempting to match many (500+) regular expressions quickly using Google's RE2 Library, as I'd like to get similar results to this whitepaper. I'd like to use RE2-m on page 13.
From what I've seen online, the Set interface is the way to go, though I'm unsure where to get started -- I haven't been able to find Google RE2 tutorials using the set interface online. Could someone please point me in the right direction?
Just implemented this today for something I'm working on, here is a snippet for the use of future readers.
The right class to handle this using RE2 is RE2::Set, you can find the code here.
Here is an example:
std::vector<std::string> kRegexExpressions = {
R"My name is [\w]+",
R"His number is [\d]+",
};
RE2::Set regex_set(RE2::DefaultOptions, RE2::UNANCHORED);
for (const auto &exp : kRegexExpressions) {
int index = regex_set.Add(exp, &err);
if (index < 0) {
<report-error>
return;
}
}
if (!regex_set.Compile()) {
<report-error>
return;
}
std::vector<int> matching_rules;
if (!regex_set_.Match(line, &matching_rules)) {
<no-match>
return;
}
for (auto rule_index : matching_rules) {
std::cout << "MATCH: Rule #" << rule_index << ": " << kRegexExpressions << std::endl;
}
How can I set a "FAILED" via script? I have a IF and in this if I want to check is X compare to Y. If not I want to get an "FAILED". For now I get an "FAILED" in my console but the test is "PASS". I already searched other sites but found nothing about this. Hope u now what I mean.
if(pm.iterationData.get("ProfileSeries") == response.ProfileSeries){
console.log("expProfileSeries " + pm.iterationData.get("ProfileSeries") + " = "+ response.ProfileSeries);
}
else{
console.log("FAILED");
}
Add pm.test with relevant pm.expect:
pm.test('ProfileSeries should be equal', function () {
pm.expect(pm.iterationData.get("ProfileSeries")).to.equal(response.ProfileSeries);
});
I am still new to using Qt4/Dbus, and i am trying to get a list of acccess points with Qt API to send/receive Dbus messeges.
I got the following error:
org.freedesktop.DBus.Error.UnknownMethod
Method "GetAccessPoint" with signature "" on interface "org.freedesktop.NetworkManager.Device.Wireless" doesn't exist
The code is:
QStringList *netList = new QStringList();
QDBusConnection sysbus = QDBusConnection::systemBus();
QDBusInterface callNM("org.freedesktop.NetworkManager","/org/freedesktop/NetworkManager","org.freedesktop.NetworkManager.Device.Wireless",sysbus);
if(callNM.isValid())
{
QDBusMessage query= callNM.call("GetAccessPoints");
if(query.type() == QDBusMessage::ReplyMessage)
{
QDBusArgument arg = query.arguments().at(0).value<QDBusArgument>();
arg.beginArray();
while(!arg.atEnd())
{
QString element = qdbus_cast<QString>(arg);
netList->append(element);
}
arg.endArray();
}else{
std::cout<< query.errorName().toStdString() << std::endl;
std::cout<< query.errorMessage().toStdString() << std::endl;
}
int x= netList->size();
for(int y=0; y< x ;y++)
{
widget.avail_nets->addItem(netList->at(y)); // just print it to my gui from the stringlist array
}
}else{
std::cout<<"fail" << std::endl;
}
Whats wrong?My naming was correct and I am following the exact specs from here
The method name is GetAccessPoints.
While your error is:
org.freedesktop.DBus.Error.UnknownMethod
Method "GetAccessPoint" with signature
"" on interface
"org.freedesktop.NetworkManager.Device.Wireless"
doesn't exist
Highlight on "GetAccessPoint". Thus you might have misspelled the method name in the code, although the code you pasted here uses the correct method name, maybe you fixed it and forgot to rebuild or clean the project?
I had the same issue, but then I noticed that it only happened when I called the GetAccessPoints method on a wired device. Make sure the device is a wireless device (i.e. DeviceType equals NM_DEVICE_TYPE_WIFI), and everything should work fine.
i modify this and works for me
QDBusInterface callNM("org.freedesktop.NetworkManager","/org/freedesktop/NetworkManager/Devices/0","org.freedesktop.NetworkManager.Device.Wireless",sysbus);
and the result is
"/org/freedesktop/NetworkManager/AccessPoint/2"
"/org/freedesktop/NetworkManager/AccessPoint/1"
i think /org/freedesktop/NetworkManager is not correct path for specific device (wireless devices).
QDBusInterface dbus_iface("org.freedesktop.NetworkManager", "/org/freedesktop/NetworkManager/Devices/0", "org.freedesktop.NetworkManager.Device.Wireless", bus);
QDBusMessage query = dbus_iface.call("GetAccessPoints");
if(query.type() == QDBusMessage::ReplyMessage) {
QDBusArgument arg = query.arguments().at(0).value<QDBusArgument>();
arg.beginArray();
while(!arg.atEnd()) {
QString element = qdbus_cast<QString>(arg);
netList->append(element);
showAccessPointProperties(element);
}
arg.endArray();
} else {
qDebug() << "got dbus error: " << query.errorName();
qDebug() << "check the parameters like service, path, interface and method name !!!";
}
Hope this will help.
