I'm trying to install pycuda on Linux Mint with a GeForce 960M and Cuda 8.0 installed. When I run the test_driver.py script it outputs the following error:

I'm using Detectron2 to do instance segmentation as in the tutorial. Below is the code:
from detectron2.config import CfgNode
import detectron2.data.transforms as T
from detectron2.data import build_detection_train_loader, DatasetMapper
os.makedirs(cfg.OUTPUT_DIR, exist_ok=True)
transform_list = [
# T.Resize(shape=(200,300)),
T.RandomRotation(angle=90.0),
# T.RandomContrast(intensity_min=0.75, intensity_max=1.25),
# T.RandomBrightness(intensity_min=0.75, intensity_max=1.25),
# T.RandomSaturation(intensity_min=0.75, intensity_max=1.25),
# T.RandomLighting(scale=0.1),
T.RandomFlip(),
# T.RandomCrop(crop_type="absolute", crop_size=(180, 270))
]
# custom_mapper = get_custom_mapper(transfrom_list)
custom_mapper = DatasetMapper(
cfg,
is_train=True,
augmentations=transform_list,
use_instance_mask=True,
instance_mask_format="bitmask",
)
class CustomTrainer(DefaultTrainer):
#classmethod
def build_test_loader(cls, cfg: CfgNode, dataset_name):
return build_detection_test_loader(cfg, dataset_name, mapper=custom_mapper)
#classmethod
def build_train_loader(cls, cfg: CfgNode):
return build_detection_train_loader(cfg, mapper=custom_mapper)
cfg.INPUT.MASK_FORMAT = 'bitmask'
cfg.DATALOADER.FILTER_EMPTY_ANNOTATIONS = False
trainer = CustomTrainer(cfg)
# trainer = DefaultTrainer(cfg)
# trainer.resume_or_load(resume=False)
# trainer.train()
However, in this case I don't care about instances and more like I want to do semantic segmentation but there is no tutorial or examples to do that nor I'm seeing a semantic model I can start with. Misc/semantic_R_50_FPN_1x.yaml throws an error saying there is no pretrained model available.
So instead I'm trying to use the SemSegEvaluator instead of COCO evaluator to give me metrics around semantic rather than instances. Below is the code:
from detectron2.evaluation import COCOEvaluator, inference_on_dataset, SemSegEvaluator
from detectron2.data import build_detection_test_loader
cfg.MODEL.ROI_HEADS.SCORE_THRESH_TEST = 0.4
# evaluator = COCOEvaluator(val_dataset_name, output_dir=os.path.join(cfg.OUTPUT_DIR, 'val'), use_fast_impl=False, tasks=['segm'])
evaluator = SemSegEvaluator(val_dataset_name, output_dir=os.path.join(cfg.OUTPUT_DIR, 'val'))
val_loader = build_detection_test_loader(cfg, val_dataset_name)
eval_result = inference_on_dataset(predictor.model, val_loader, evaluator)
print(eval_result)
However, this is failing with the following error:
[12/20 16:29:02 d2.data.datasets.coco]: Loaded 50 imagesss abdul in COCO format from /content/gdrive/MyDrive/SolarDetection/datasets/train8//val/labels.json

Any idea or hint how I can setup and use the SemSegEvaluator?

I was following a tutorial in the pytest documentation for creating temporary directories, https://docs.pytest.org/en/stable/tmpdir.html and when I executed the following code, the contents of my entire documents folder was deleted.
import pytest
import os
#pytest.fixture()
def tmdirmak(tmpdir_factory):
f = tmpdir_factory.mktemp("data")
return f
def test_temp(tmp_path):
d = tmp_path / "sub1"
d.mkdir()
p = d / "tem.txt"
p.write_text("hello")
assert p.read_text() == "hello"
os.system("ls")
This file was saved in my documents folder and this is where I ran the command pytest --basetemp=. -s test_paths.py which accounting to the documentation is how you change where the temporary directory is made. I did not want the temporary directory to be made in /tmp but rather I wanted it created in the same directory that my code lives. When I ran this I got the following pytest output

I think returned to find all my folders and documents in my documents directory to be deleted! I suspect since pytest normally thinks it is in /tmp it just clears out all the stuff in that folder when it is done, including the things it didn't create. If this is true, this is a horrible bug. What's strange is I received these permission errors yet my contents were deleted anyway.
I'm trying to do some basic module setups on my server using Python. Its a bit difficult as I have no access to the internet.
This is my code
import sys
import os
from subprocess import CalledProcessError, STDOUT, check_output
def run_in_path(command, dir_path, env_var=''):
env_var = os.environ["PATH"] = os.environ["PATH"] + env_var
print(env_var)
try:
p = check_output(command, cwd=dir_path, stderr=STDOUT)
except CalledProcessError as e:
sys.stderr.write(e.output.decode("utf-8"))
sys.stderr.flush()
return e.returncode
else:
return 0
def main():
requests_install = run_in_path('python setup.py build',
'D:\installed_software\python modules\kennethreitz-requests-e95e173')
SQL_install = run_in_path('python setup.py install', # install SQL module pypyodbc
'D:\installed_software\python modules\pypyodbc-1.3.3\pypyodbc-1.3.3')
setup_tools = run_in_path('python setup.py install', # install setup tools
'D:\installed_software\python modules\setuptools-17.1.1')
psycopg2 = run_in_path('easy_install psycopg2-2.6.1.win-amd64-py3.3-pg9.4.4-release', # install setup tools
'D:\installed_software\python modules', ';C:\srv_apps\Python33\Scripts\easy_install.exe')
print('setup complete')
if __name__ == "__main__":
sys.exit(main())
now it gets tricky when i start trying to use easy install. It appears my env variables are not being used by my subprocess.check_output call
File "C:\srv_apps\Python33\lib\subprocess.py", line 1110, in _execute_child
raise WindowsError(*e.args)
FileNotFoundError: [WinError 2] The system cannot find the file specified
I don't want to have to upgrade to 3.4 where easy install is installed by default because my other modules are not supported on 3.4. My main challenge is the subprocess.check_call method does not take environment variables as an input and im wary of trying to use Popen() as I have never really got it to work successfully in the past. Any help would be greatly appreciated.
PATH should contain directories e.g., r'C:\Python33\Scripts', not files such as: r'C:\Python33\Scripts\easy_install.exe'
Don't hardcode utf-8 for an arbitrary command, you could enable text mode using universal_newlines parameter (not tested):
#!/usr/bin/env python3
import locale
import sys
from subprocess import CalledProcessError, STDOUT, check_output
def run(command, *, cwd=None, env=None):
try:
ignored = check_output(command, cwd=cwd, env=env,
stderr=STDOUT,
universal_newlines=True)
except CalledProcessError as e:
sys.stderr.write(e.output)
sys.stderr.flush()
return e.returncode
else:
return 0
Example:
import os
path_var = os.pathsep.join(os.environ.get('PATH', os.defpath), some_dir)
env = dict(os.environ, PATH=path_var)
run("some_command", cwd=some_path, env=env)
run("another_command", cwd=another_path, env=env)
I am using selenium and i have properly installed the selenium module on redhat linux 6.

When i am running this script it is showing errors:

Please help me for this...
Thanks in advance!
Simple: Selenium can't find an element called "Bugzilla_login".
There could be hundreds of reasons this may be happening. I'd start with checking whether you're loading the correct page.
