[Solved] dyld: Library not loaded: /System/Library/Frameworks/Network.framework/Network

Question:

Today’s test brought a low version of iPhone. I ran the project with it and reported the following errors
dyld: Library not loaded: /System/Library/Frameworks/Network.framework/Network
Referenced from: /var/containers/Bundle/Application/CD697C3E-135B-4A33-BA7B-D95D33E24070/巨折.app/巨折

Solution:

Follow the prompts and go to Build Phases -> Link Binary With Libraries and add Network.framework

After running it still reports the same error, then you need to go to Link Bnary With Libraries and set Network to Optional.

The reason for this error is that there is a null value in the dataframe attribute in the previous processing, using na.drop() is removed and the error is resolved.

df05=df05.select("direction","station_name","order_no","lat","lng").na.drop()

HLS ERROR: [IMPL 213-28] Failed to generate IP. [How to Solve]

Problem Description:

The following problems occur when using HLS to synthesize or package IP
error: [impl 213-28] failed to generate IP
command ‘ap_ Source ‘returned error code

has been tested in HLS of three versions (2018.3, 2020.1 and 2020.2) successively, and all errors are reported. The existing solutions (modifying the file name) do not work

Solution:

Adjust the system time of window to be less than or equal to 2021
this problem can be solved

[Solved] Shell loop execute error: syntax error: bad for loop variable

#!/bin/bash

for ((i = 10 ; i>=0 ; i--))
do
	echo $i
done

Syntax error: bad for loop variable

The reason is that since Ubuntu 6.10, Ubuntu has replaced the previous default bash shell with dash shell; It shows that the/bin/sh link reverses/bin/dash instead of the traditional/bin/bash.

Question 1: why #/ Bin/bash doesn’t work?

./execution will read #/ Bin/bash specifies the shell parser, and the script needs execution permission

Executing with SH will not read #/ Bin/bash, which is equivalent to executing the/bin/sh shell script and passing it in as a parameter. The script does not need execution permission, but only reading permission

Solution 1:

Execute sudo dpkg reconfigure dash and select No

Solution 2:

Modify cycle

[Solved] fatal error: Eigen/Geometry: No such file or directory

Error encountered when compiling the program of Aubo manipulator. Eigen cannot be found

/opt/ros/melodic/include/moveit/robot_model/joint_model.h:47:10: fatal error: Eigen/Geometry: No such file or directory
#include <Eigen/Geometry>

Reason:
the location of eigin library is/usr/include/eigin3/eigen. The system cannot find this location. We need to link it manually

Solution:
manually create a soft link to the upper level directory

sudo ln -sf /usr/include eigen3/Eigen /usr/include/Eigen
sudo ln -sf /usr/include/eigen3/unsupported /usr/include/unsupported
