out-of-memory

问题 I need to create a lower triangular matrix with a special structure then do a matrix-vector multiplication. The matrix is parameterized by a value k . It main diagonal is a vector of k ^ 0 , i.e. 1; the first sub-diagonal is a vector of k ^ 1 , and the i -th sub-diagonal holds k ^ i . Here is a 5 x 5 example with k = 0.9 : structure(c(1, 0.9, 0.81, 0.729, 0.6561, 0, 1, 0.9, 0.81, 0.729, 0, 0, 1, 0.9, 0.81, 0, 0, 0, 1, 0.9, 0, 0, 0, 0, 1), .Dim = c(5L, 5L)) # [,1] [,2] [,3] [,4] [,5] #[1,] 1

问题 We are storing string fields which varies in length from small(few kB) to very long(<400MB) in HIVE table. Now we are facing the issue of OOM when copying data from one table to another(without any conditions or joins), which is not exactly what we are running in production, but it is the most simple use case where this problem occurs. So the HQL is basically just: INSERT INTO new_table SELECT * FROM old_table; Container and Java Heap was set to 16GB, we had tried different file formats

问题 Want to build a 3D Bar Chart using Mayavi (on my Asus Laptop Intel CoreTM i7-4510U CPU @ 2.00 GHz with 8 GBs de RAM, Windows 10) using a Jupyter Notebook (on a Python virtualenv) but I'm getting a grey screen. Once the data was imported, I clicked in New > Python 3 and wrote Used pandas' fast CSV parser, pandas.read_csv(), and once I ran line 4, I could see the memory usage increase to 88% of the capable using CleanMem Mini Monitor and got results in less than 1 minute. Then, to build the bar

问题 I am executing rules for a decision table using statelessKieSession. I have 1000 objects and 10 rules for each object so total I have 10000 rules for one row. Rules will process for each row in the decision table. Currently before finishing the execution of one row I am getting OutOfMemory error. Any idea about this issue? From the below link you can refer the memory usage details and find the classes which creates more instances while executing the rules. 来源： https://stackoverflow.com

问题 My app consists from 4 layout files, each layout uses a different image as background. I manage to load layout 1 and 2, but after I go to layout 3 I get error "Caused by: java.lang.OutOfMemoryError" I suspect it's because the layout 1 and layout 2 is still in the memory. Any way is there a way to clean memory everytime I go to a new layout so I don't run out of memory? Thanks. P.S I use Android Studio. P.S 2 I'm not sure if this changes anything but just in case this is how I go to different

问题 I have a script partially based on the one here: Upload files with FTP using PowerShell It all works absolutely fine with tiny files but I am trying to use it to make the process we use for exporting access mdb files to clients that only have ftp more robust. My first test involved a 10MB file and I ran into a System.OutOfMemoryException at the Get-Content stage The powershell ISE was running to nearly 2GIG usage during the get attempt. Here is a full script sample (Be gentle. I am fairly new

问题 In my app I'm loading plenty of images from the web. That's working fine so far: @Override public void onSuccess( byte[] response ) { Bitmap image = BitmapFactory.decodeByteArray( response, 0, response.length, options ); ... } But in fact it would be nice to use only an extract of the image during the application process. So I tried something like this: @Override public void onSuccess( byte[] response ) { Bitmap source = BitmapFactory.decodeByteArray( response, 0, response.length, options );

问题 Im getting an OutOfMemory Exception when using this code: class ApiTask extends AsyncTask<URI, Void, String> { private Exception exception; protected void onPreExecute() { dialog = ProgressDialog.show(DownloadedActivity.this, "", "Contacting Server...", true); } protected String doInBackground(URI... uri) { try { HttpClient client = new DefaultHttpClient(); HttpGet request = new HttpGet(); try { request.setURI(uri[0]); return client.execute(request, new BasicResponseHandler()); } catch

问题 I have 3 images taken from camera and I want to set to 3 ImageView. But it throws OutOfMemory because the image has large size. I've read that bitmap factory can compress the size without reducing the quality. The problem is I don't know how to do that. This is my onClick Button: openCameraButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); file = new File(Environment

问题 [There was an initial question at OOM in tez/hive but after some answers and comments a new question with the new knowledge is warranted.] I have a query with a large LATERAL VIEW. It joins 4 tables, all ORC compressed. The buckets are on the same column. It goes like: select 10 fields from t , 80 fields from the lateral view from ( select 10 fields from e (800M rows, 7GB of data, 1 bucket) LEFT JOIN m (1M rows, 20MB ) LEFT JOIN c (2k rows, <1MB) LEFT JOIN contact (150M rows, 283GB, 4 buckets
