I'm implementing Dreambooth-Stable-Diffusion On Google Colab.
I was able to install coda replicate the same steps mentioned in the repo above, and generate the regulation images successfully. However, I'm getting pytorch_lightning.utilities.exceptions.MisconfigurationException: No test dataloader() method defined to run Trainer.test after running the Training command.
Here is the full log:

I tried this solution - even though it was hard to know where to exactly put the edit and I'm not 100%, but still, it didn't work.

I am building an application backed by a Neptune database. Because I want the application to be scalable, I am using AWS Lambda + API gateway to build a REST API to interact with the database. This seems to be a reasonable idea based on the fact that this use case is documented in the Neptune docs.
The Neptune docs recommend reusing the websocket connection to the database across the entire execution context of the function, which is what I am doing at the moment. The docs also recommend resetting the connection and retrying upon errors (see here), which I am also using. However, I am seeing exceptions every now and then (perhaps every 20 requests on average). One of the exceptions I get is
ConnectionResetError: Cannot write to closing transport
which seems to be the same as this issue.
The other one is:

In case it is relevant, I am using gremlingpython==3.5.1
It seems to me that these issues are all ultimately a consequence of using AWS Lambda, namely due to the mismatch between the longevity of websocket connections and the ephemeral nature of lambda execution contexts. The question then is: Am I doing the wrong thing by trying to use AWS lambda for my API? Would it be more appropriate to setup an EC2 instance and deal with the scalability in some other way?
P.S. Previously I did create and close a connection in every function execution (as previously recommended in the Neptune docs), which did work fine but was naturally slow.
The latest version of Neptune only supports Gremlin 3.4.11 (https://docs.aws.amazon.com/neptune/latest/userguide/engine-releases-1.0.5.1.html). I would start by using gremlin-python 3.4.11 and see if that resolves your issue. Gremlin-python 3.5 replaced Tornado with AIO HTTP (ref) for websocket connections and I suspect that change may be causing a slight change in behavior that a future release supporting Gremlin 3.5 will address.
I wonder whether the 'Connection was already closed' error message is not being treated as a retriable error by the retry logic?
What happens if you add this error message to the list of retriable_error_msgs in the Python example in the docs?
I define one spider with name='myspider', its behavior would be different according to the setting.And I want to run the spider with different instances in different process, is it possible?
I check the source code,it seems the SpiderLoader just walk the spiders module and I could just run one spider with the same name one time.
the running code seems:
for item in items:
settings = get_project_settings()
settings.set('item', item)
settings.set('DEFAULT_REQUEST_HEADERS', item.get('request_header'))
process = CrawlerProcess(settings)
process.crawl("myspider")
process.start()
and of course, the error shows:
Traceback (most recent call last):

Thanks advance for any help!
Setting cannot be changed at runtime.
I suggest you to use spider argument to pass different variable to spider.
process = CrawlerProcess(settings)
process.crawl("myspider", request_headers='specified headers...')
process.start()
And for doing this, you have to override init function of your spider to accept these variables. And pass the request_header to every Request object you use in the spider.
def __init__(self, **kw):
super(MySpider, self).__init__(**kw)
self.headers = kw.get('request_headers')
...
yield scrapy.Request(url='www.example.com', headers=self.headers)
I'm trying to use twisted to handle data generated by a binary (which indefinitely dumps lines onto stdout). Since by data is inherently line-delimited, I was trying to used the LineReciever instead of trying to parse data. The following is the relevant bit of the code which seems to be causing trouble :
class ProtocolBareQDAL41xB(ProcessProtocol, LineReceiver):
...
def outReceived(self, data):
print "Got Data:" + repr(data)
self.dataReceived(data)
def lineReceived(self, line):
print "Got Line: " + line
self._process_line(line)
...
This 'works' for the first of two lines in the output. I don't know yet if it works for only one line, or if it works for all but the last line. The resulting output looks something like :
$ python BareQDAL41xB.py
Made Connection
<Process pid=16486 status=-1>
Got Data:'No device found!\nMultiple devices found! Please connect only one.\n'
Got Line: No device found!
Got Serial Number : found!

self.transport.disconnecting):

LineReciever seems to be expecting the transport to implement disconnecting.
Is it possible to use twisted's LineReciever with twisted's ProcessProtocol, or should I implement the line parser in my protocol instead?
LineReceiver is already a Protocol, which implements different interfaces than IProcessProtocol.
Luckily, recent versions of Twisted already contain an adapter that does what you want - which is to treat a subprocess as a stream of bytes. Rather than calling spawnProcess directly, use ProcessEndpoint, and you can pass a regular ProtocolFactory, no ProcessProtocol involved.
However, as a commenter has already pointed out, there's a bug here, where the disconnecting attribute is not formally part of ITransport, but LineReceiver (and LineOnlyReceiver) depend on it anyway, and since it's not part of the interface, ProcessEndpoint doesn't implement it. That should definitely be fixed, but in the meanwhile, we'll need to work around it.
As a happy accident, Twisted's built-in support for wrapping protocols, WrappingFactory, already has support for the disconnecting attribute, specifically because of this ugly disparity between the theory of the interface specifications and the reality of the most popular ITransport implementations. So even a do-nothing wrapper will work around the problem. You can implement this like so:
from zope.interface import implementer
from twisted.internet.interfaces import IStreamClientEndpoint
from twisted.protocols.policies import WrappingFactory
#implementer(IStreamClientEndpoint)
class DisconnectingWorkaroundEndpoint(object):
def __init__(self, endpoint):
self._endpoint = endpoint
def connect(self, protocolFactory):
return self._endpoint.connect(WrappingFactory(protocolFactory))
and then when you construct your ProcessEndpoint, do:
endpoint = DisconnectingWorkaroundEndpoint(ProcessEndpoint(...))
Sorry for the delay on answering; while you've probably worked out your own workaround, I hope this will be useful to others with the same question!
The issue I'm having is that I'm trying to build an Angstrom image from scratch using bitbake (since Angstrom is now Yocto Compatible) but I've run into an error the moment I run the bitbake systemd-image

I've been at this for a while now, searching on different sites. Originally I tried following the guide at the developer section on the Angstrom site, but once I got some errors (prior to this one I'm putting here), I found Derek Molloy's site http://derekmolloy.ie/building-angstrom-for-beaglebone-from-source/ which solved those errors and gave a little more detail into the process.
Eventually I stumbled onto another forum post which decribed my problem, but unfortunately the answers weren't really clear (for me anyway) http://comments.gmane.org/gmane.linux.distributions.angstrom.devel/7431. I'm at a loss on what could be wrong, and I'm pretty much new to Yocto project so I'm unsure if there's any steps missing or something that's implicit that I have overlooked, so I would deeply appreciate anyone who could point me on the right direction on this.
As side note, I've been thinking that it could be something having to do with the environment-angstrom-... file that I have, since mine is environment-angstrom-v2013.12 and all the other examples use previous versions, I'm wondering if there's a new step involved when working with this.
Is there a reason why you are using a system-wide bitbake instead of the one that is compatible with that release of Angstrom?
Don't use a system-wide bitbake, as the bitbake API can and does change over time. Use the corresponding bitbake for that release of angstrom.
(This is breaking because your bitbake requires getVar to take three arguments but your angstrom layers are only passing two)
Migration from plone 3.3.2 to plone 4.2.1 fails with PosKeyError. I've tried recipes from this article http://plonechix.blogspot.com/2009/12/definitive-guide-to-poskeyerror.html.
I've run error_finder snippet, but it didn't give me any execeptions. I've also tried to take object in debugger using app.mysite._p_jar[p64(oid)] - also no success, it fails with the same error.
How can I delete the broken object or at least get more info about object (e.g. its class name or location)?

You can use the fsrefs.py to find the bad object.
A very short article on using it is: http://nathanvangheem.com/news/fixing-broken-zodb-object-references
I believe this is the same issue I just ran into which happens if a savepoint is rolled back that included adding an object to the catalog. I think this is a bug in the ZODB but you can workaround it by addressing whatever is rolling back a savepoint, in this case that's the migration of files and images to blobs. So if you fix what's keeping those files or images from successfully migrating to BLOBs (or just delete them) then it should succeed.
