I'm new in Laravel, I use laravel 5.2 and I'm trying to generate a report using DomPdf but I'm getting error:

I was having this same problem, and I found a solution that makes no sense to me.
The HTML I was passing to dompdf didn't have any line breaks, like:
<html><body>content here<body></html>
Adding a break after the body tag fixed the problem.
<html><body>
content here
</body></html>
No clue what's going on, but now it works. Hope this fixes your problem too.

I want to edit a tree that I got from BEAST2 treeannotator in nexus-format.
Usually I use the module Phylo from Biopython for such work but Phylo.read(r"filename.tree", "nexus") gave me the next exception:

Using Nexus.read(Nexus(), input=r"filename.tree") gave the same result. Please could anyone help with this? I cannot understand the reason of this error because nexus file looks correct.
The reason is that Biopython cannot read nexus trees with links, constituent from translations & a newick tree. So it is required previously to convert this to the form with full names into the tree (as hereinbelow).
Begin
tree TREE1 = (((your,tree),(in,(the, newick))),format);
End;
P.S. It is allowed in the newick format to surround the label with quotes, & some programmes or scripts add them to those names that have ambiguous characters. But it can lead to exceptions during the following phylogenetic analysis, for instance, in BEAST. I wish you would be careful with this.
I'm new to Anaconda. I tried to execute Pytorch Adversarial Neural Network in anaconda. It shows some error that I have no clue. Here is the code that downloads dataset
# MNIST Test dataset and dataloader declaration
test_loader = torch.utils.data.DataLoader(datasets.MNIST('../data', train=False, download=True, transform=transforms.Compose([
transforms.ToTensor(),])),batch_size=1, shuffle=True)
This is the error message I got :

How about changing the '../data' to another directory, like '/Users/***/Downloads/data' or somewhere else.
I have problem with golang zip reader. We have apk builder which build apk and then encrypted this apk with dex protector.
When i try to open apk file, go return err "zip: not a valid zip file". But when i try to open with unzip or zipinfo, worked fine.
(Also I noticed something interesting: in php 5.5 apk file opened with ZipArchive fine, but in 5.6 return error like golang)
I try open to debug golang archive/zip pckage and found that error returned in this line https://github.com/golang/go/blob/master/src/archive/zip/reader.go#L269.
Then i try to debug this line like this:
fmt.Printf("%+v", f)
fmt.Println(
"len(f.Extra):", len(f.Extra),
"len(b):", len(b),
"tag:", tag,
"size:", size,
)
And have this results:

Problem in extra headers (i think this extra headers add dex protector when encrypt apk). Size more then length of extra bytes.
But unzip util and ZipArchive in php5.5 woked perfect with this extras. How to fix this ?
I want to rewrite this piece in go archive/zip package, so that the extras do not interfere golang zip reader.
It's very important for me, because i rewrite build apk from php to golang and I came across a problem that can not decide :(. Please help me.
I got the following notices and would like to clarify:

Code lines in the compiled tpl are:
<?php if ($_smarty_tpl->tpl_vars['TablesLinked']->value[$_smarty_tpl->getVariable('smarty')->value['section']['i']['index']]){?>
This is the uncompiled line:
{if $TablesLinked[i]}
One line above starts the section:
{section name=i loop=$NumberFields}
Do I have to change the start index because offset means wrong index ?
TablesLinked does not appear in every field, because fields consist of linkedtables and normal fields, thats why I use an if-clause.
I hope you can help.
Although it is a very good practice set error_reporting to E_ALL during development phase and trying to eliminate all notices, personally I wouldn't worry about these messages. It just won't find the elements on the specified indices during the loop. In any case, if you insist on eliminating the notices, you can change
{if $TablesLinked[i]}
to
{if isset($TablesLinked[i]) && $TablesLinked[i]}
In the following code:
139 struct rlimit limit;
140
141 method = "rlimit";
142 if (getrlimit(RLIMIT_NOFILE, &limit) < 0) {
143 perror("calling getrlimit");
144 exit(1);
145 }
146
147 /* set the current to the maximum or specified value */
148 if (max_desired_fds)
149 limit.rlim_cur = max_desired_fds;
150 else {
151 limit.rlim_cur = limit.rlim_max;
152 }
153
154 if (setrlimit(RLIMIT_NOFILE, &limit) < 0) {
155 perror("calling setrlimit");
156 exit(1);
157 }
the setrlimit line fails (I get the error "calling setrlimit"). Further investigation shows that limit.rlim_max is -1, which is not a valid value. Any ideas why would this be? This is on Mac OSX.
If setrlimit fails, try again with rlim_cur set to OPEN_MAX. For example, see http://source.winehq.org/source/libs/wine/loader.c#L653. (The comment mentioning Leopard means that Leopard first introduced that behavior. Read it as Leopard-and-later.)
ETA: See the note in COMPATIBILITY in the setrlimit(2) man page.
