4 errors detected in the compilation of "C:/Users/18295/AppData/Local/Temp/tmpxft_00003514_00000000-10_ROIAlign_cuda.cpp1.ii"

Solution:

Modify maskscoring_ rcnn/maskrcnn_ benchmark/csrc/cuda/ROIAlign_ Cuda.culine 275:

//Original code: dim3 grid(std::min(THCCeilDiv(output_size, 512L), 4096L));
dim3 grid(std::min(((int)output_size + 512 -1)/512, 4096));

Mask scoring/maskrcnn benchmark/csrc/cuda/ROIAlign cuda.cu3203

//Original code: dim3 grid(std::min(THCCeilDiv(grad.numel(), 512L), 4096L));
dim3 grid(std::min(((int)(grad.numel()) + 512 -1)/512, 4096));

Modify maskscoring_rcnn/maskrcnn_benchmark/csrc/cuda/ROIPool_cuda.cu Line129:

// dim3 grid(std::min(THCCeilDiv(output_size, 512L), 4096L));
dim3 grid(std::min(((int)output_size + 512 -1)/512, 4096));

Modify maskscoring_rcnn/maskrcnn_benchmark/csrc/cuda/ROIPool_cuda.cu line 176:

//dim3 grid(std::min(THCCeilDiv(grad.numel(), 512L), 4096L));
dim3 grid(std::min(((int)(grad.numel()) + 512 -1)/512, 4096));

After modification, execute Python setup.py build development

Error 2:

error: ROIAlign_ Cuda.cu and roipool_ “In cuda.cu file”__ Floorf “and”__ Ceilf “error

error: calling a __host__ function("__floorf") from a __device__

error: calling a __host__ function("__ceilf") from a __global__ 
function("detectron2::RoIAlignRotatedForward<float> ") is not allowed
error: identifier "__ceilf" is undefined in device code

Solution:

Find roialign_ Cuda.cu and roipool_ Cuda.cu file, add F after ceil and floor , that is, ceil is changed to ceilf , floor is changed to floor
the successful implementation is as follows:

Problem description

Using pyinstaller to package the project into an executable file, we encountered the above problems after solving various problems. The project we wrote needs to use multiple processes, but this problem will occur if the process is not successfully created.

Solution 1

I think others’ solutions are as follows:

if __name__ == '__main__':
	# The following sentence must be added below the if
	multiprocessing.freeze_support()

Solution 2

The general search answer is scheme 1, but this does not apply to me. As a result, the problem bothered me for two days. Just realized that if you use argparse in your code, package it into an executable file, and use multiple processes, you are likely to report this error. After I modified argparse and packaged it into an executable file, multiple processes can be started normally.

[Solved] Run sudo python setup.py install Error: error: error in setup.cfg: command ‘build‘ has no such option ‘i18

1. Problem description

Error: error in setup.cfg: Command ‘build’ has no such option ‘I18N’ when running sudo Python setup.py install in the installation package of Ubuntu system

2. Solutions

Other dependent environments need to be installed:

Python distutils extra needs to be installed

sudo apt-get update -y
sudo apt-get install -y python-distutils-extra

Then run it again

sudo python setup.py install

[Solved] cv2.error: OpenCV(4.5.3) :-1: error: (-5:Bad argument) in function “pointPolygonTest“

python   Running error: CV2. Error: opencv (4.5.3): – 1: error: (- 5: bad argument) in function “pointpolygontest”

The solution is simple because the CV2 version is not compatible

Step 1: uninstall the installed version

Step 2: install the old version

Step 3:   Confirm successful installation

The above error will not be reported during operation.

cv2 error – function not implemented [How to Solve]

Recall that Anaconda was installed later and uninstalled first. Sure enough, the original opencv relied on Python 3.8 of Ubuntu 20.04.

python cx_Oracle.DatabaseError: Error while trying to retrieve text for error ORA-01804

Problem Description:

Using Python package CX_ When setting scheduled tasks on the Oracle server, errors are always reported, such as the title, but running alone is no problem

resolvent:

Under the guidance of the boss, add a few lines of code in front of the script to solve the problem perfectly. The environment variable path is configured according to its own path.

import os

os.environ["ORACLE_HOME"] = '/home/oracle/app/oracle/product/11.2.0/dbhome_1'

fatal error: Python.h: No such file or directory

fatal error: Python.h: No such file or directory

Process: through PIP install a library, an error occurred and the python. H header file could not be found

Solution

Search stackoverflow. My environment is CentOS, so execute sudo Yum install python3 devel and then go to the PIP install library. It’s all OK

For apt (Ubuntu, Debian…):

sudo apt-get install python-dev   # for python2.x installs
sudo apt-get install python3-dev  # for python3.x installs

For yum (CentOS, RHEL…):

sudo yum install python-devel    # for python2.x installs
sudo yum install python3-devel   # for python3.x installs

For dnf (Fedora…):

sudo dnf install python2-devel  # for python2.x installs
sudo dnf install python3-devel  # for python3.x installs

For zippers (openSUSE):

sudo zypper in python-devel   # for python2.x installs
sudo zypper in python3-devel  # for python3.x installs

For apk (Alpine…):
This is a departure from the normal Alpine naming
scheme, which uses py2- and py3- prefixes

sudo apk add python2-dev  # for python2.x installs
sudo apk add python3-dev  # for python3.x installs

For apt-cyg (Cygwin…):

apt-cyg install python-devel   # for python2.x installs
apt-cyg install python3-devel  # for python3.x installs

The TCP port is occupied. Start multiple jobs on one computer. You need to specify a different port for each job (29500 by default) to avoid communication conflict
the solution is to specify the port while running the program, and give the port number arbitrarily before the PY file to be executed:

python -m torch.distributed.launch --nproc_per_node=1 --master_port 66660  ./tools/train.py ~/project/cp3/CenterPoint/work_dirs/voxel_config/nusc_centerpoint_voxelnet_0075voxel_fix_bn_z.py

Another way is to find the occupied port number (insert print output in the program), then find the PID value corresponding to the port number: netstat – nltp, and then cancel the occupation of the port through kill – 9 PID.
