ForEach Object Error #920

markusvonplunkett · 2018-01-03T20:11:24Z

I have just updated to the latest version of MPM (v2.7.1.0) and I am getting the following error when running and occasionally whilst mining:

`ForEach-Object : You cannot call a method on a null-valued expression.

Had the same issue on a fresh install that I interrupted during benchmarking. Ran ResetBenchmark and it cleared the issue.

almothafar · 2018-01-05T21:36:44Z

Got the same issue, ResetBenchmark not worked for me, I followed all important notes but was not helpful.

Please try after deleting ALL files in the stats folder.

almothafar · 2018-01-08T10:18:59Z

@UselessGuru I really tried that many times, and even with a fresh version, by removing all files, extract the files again and modifying .bat files and run it again.

UselessGuru · 2018-01-08T11:10:52Z

@almothafar

Does the error occur already on first start, or after subsequent runs?

The error comes from reading one of the files in one of the following directories:
\Stats
\Pools
\Miners

We have to find out which file is causing it. Can you do a fresh install (yes - once more). Do NOT edit any files!

Then BEFORE you start:

remove all miner files (stats folder is still empty)
Run MPM -> error still here? You might get 'no miners available' - that expected
If yes, remove all stats files, remove all but on pool files
Run MPM -> Error still here? -> If yes than I am puzzled
if not (you will see no miners available, but that's expected), then add another pool file, delete all stats, run MPM again. Loop until you find the Pool file causing problems
-If all pools are working then:
Put the miner files back one by one, alwas deleting all the stat before each try.

Also could you please upload the logs for the problematic run.

Please note that future releases will include extra functionality to aid debugging this like this.

almothafar · 2018-01-11T21:26:25Z

@UselessGuru actually the issue was happening with any Miner, without miners, I get no issues but the warning.

For pools I have only "MiningPoolHub.ps1" and "MiningPoolHubCoins.ps1", I don't need anything else anyway.

Edit:

And this is will all pools in:

Still in progress but you can many issues.

aaronsace · 2018-01-11T21:36:44Z

There is something wrong with your opencl.dll that is needed for the AMD miner files like sgminer.

Exception calling "GetPlatformIDs" with "0" argument(s): "OpenCl error -1001: -1001."

OpenCL support is included in the latest NVIDIA GPU drivers, available at www.nvidia.com/drivers

almothafar · 2018-01-11T21:44:15Z

@aaronsace

I have the version of nVidia driver is 388, currently, I'm updating it to 390

Anyway, this is the log file for just extract and run, nothing changed:
2018-01-11_23-38-58.txt

aaronsace · 2018-01-11T21:45:53Z

Same error; OpenCL. Delete the miner files for now.

aaronsace · 2018-01-11T21:48:22Z

This is the function that the AMD miner files use that's not working:

public static Platform[] GetPlatformIDs()
{
	ErrorCode error;
	uint count;

	error = NativeMethods.clGetPlatformIDs(0, null, out count);
	if (error != ErrorCode.Success) {
		throw new OpenClException(error);
	}

	var ids = new IntPtr[count] ;
	error = NativeMethods.clGetPlatformIDs(count, ids, out count);
	if (error != ErrorCode.Success) {
		throw new OpenClException(error);
	}

	var res = new Platform[count];
	for (var i=0; i<count; i++) {
		res[i] = new Platform(ids[i]);
	}
	return res;
}

almothafar · 2018-01-11T21:49:04Z

Why it is AMD I got Intel here, is it normal?

aaronsace · 2018-01-11T22:07:02Z

There has been 23 commits to the wrapper that I'm using, maybe it's been fixed:
https://github.com/aaronsace/opencl-sharp

@almothafar Does this fix any of the OpenCL issues:
OpenCL.zip

aaronsace · 2018-01-11T22:13:08Z

@almothafar You have NVidia not Intel.

almothafar · 2018-01-11T22:37:43Z

Oh nvm, I thought it is CPU not GPU, anyway, I tried new OpenCL files and have no logs, only the following errors:

Fixed compilation issues, try now:

Send me the output of 'Test.bat'.

Still failing, test.bat output was:

Try running the test bat as an admin; do you get the same output?

Are you using remote desktop?

Have you tried completely uninstalling the driver then downloading and installing the new one?

aaronsace · 2018-01-14T16:43:49Z

I've found an official NVidia test example:
oclDeviceQuery.zip

If that works then I know it's something wrong with what I'm doing.
If that doesn't work then I know there is something wrong with your system.

almothafar · 2018-01-14T18:04:31Z

I was always doing run as administrator.
No, I'm on the machine.
Yes, many times, and I tried to see if any of those drivers software can fix driver issues (if found any), like Device Doctor, Driver Booster and so on.

For the Device Query, it seems not working, so it is my system?
oclDeviceQuery.txt

aaronsace · 2018-01-14T18:15:56Z

Must be, as it says here that OpenCL is included in that drivers link and has the example usage below:
https://developer.nvidia.com/opencl

From the perspective of getting MultiPoolMiner to run, delete any files in the folder called 'miners' that contain the word 'opencl'.

almothafar · 2018-01-14T18:41:59Z

Thanks for your efforts, I started the benchmark now and it seems going without any error as initial run, not completed the run yet it is ongoing now
