  1. If you are still getting the error "Could not load dynamic library 'libnvinfer.so.7'; dlerror: libnvinfer.so.7: cannot open shared object file: No such file or directory" after installing the library, there may be a few other things you can try to fix the problem. Here are a few suggestions:
  2.  
  3. Make sure that the library is installed in a location that is in your system's library search path. You can check the library search path by running the following command:
  4.  
  5.  
  6.  
  7. echo $LD_LIBRARY_PATH
  8.  
  9.  
  10. If the directory where the library is installed is not listed in the library search path, you can add it by modifying the LD_LIBRARY_PATH environment variable. For example, you can add the following line to your ~/.bashrc file:
  11.  
  12.  
  13.  
  14. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/library
  15.  
  16.  
  17. If the library is installed in a location that is in the library search path, make sure that the library is readable and executable. You can check the permissions on the library by running the ls -l command.
  18.  
  19. If the library is installed and has the correct permissions, it is possible that there is an issue with the library itself. In this case, you may need to re-install the library or try a different version of the library.

  23. Getting this error while trying to install libnvinfer7 library: Unable to locate package libnvinfer7
  24.  
  25.  
  26. If you are getting an error saying "Unable to locate package libnvinfer7" while trying to install the libnvinfer7 library, it means that the package is not available in the package repository that you are using. This could be because the package is not available in the repository, or it could be because you are using the wrong repository.
  27.  
  28. There are a few things you can try to fix this problem:
  29.  
  30. Make sure that you have the correct repository enabled. The libnvinfer7 package may be available in a different repository than the one you are currently using. You can check the available repositories by running the following command:
  31.  
  32.  
  33. apt-cache policy
  34.  
  35.  
  36. This will show you the repositories that are enabled on your system, as well as the priority of each repository. You may need to enable a different repository or modify the priority of the repositories to make the libnvinfer7 package available.
  37.  
  38. If the libnvinfer7 package is not available in any of the enabled repositories, you may need to add a new repository to your system. You can do this by adding a new line to your /etc/apt/sources.list file. For example, you can add the following line to enable the official Ubuntu repositories:
  39.  
  40.  
  41. deb http://archive.ubuntu.com/ubuntu bionic main universe
  42.  
  43.  
  44. If the libnvinfer7 package is still not available after adding new repositories, it is possible that the package is not available for your version of Linux. In this case, you may need to try a different version of the library, or you may need to build the library from source.
  45.  
  46.  
  47.  
  48. How do you build the library from source?
  49.  
  50.  
  51. To build a library from source, you will need to download the source code for the library and compile it on your system. Here's an outline of the steps you can follow to build the libnvinfer7 library from source:
  52.  
  53. Download the source code for the library. You can usually find the source code for a library on the website of the library, or you can use a version control system like Git to download the source code.
  54.  
  55. Extract the source code from the archive. If you downloaded the source code as a compressed archive (e.g. a .zip or .tar.gz file), you will need to extract the source code using a utility like unzip or tar.
  56.  
  57. Navigate to the directory containing the source code.
  58.  
  59. Run the ./configure script to configure the build process. This script will check for any dependencies that are needed to build the library, and it will create a Makefile that can be used to build the library.
  60.  
  61. Run the make command to build the library. This will compile the source code and create the library file.
  62.  
  63. Run the make install command to install the library. This will install the library file and any necessary header files in the appropriate locations on your system.
  64.  
  65.
