Solve /sbin/ldconfig.real: /usr/local/cuda-11.8/targets/x86_64-linux/lib/libcudnn_ops_infer.so.8 is not a symbolic link

I received this error when installing packages in Ubuntu 23.10. To solve this issue, you can fix the CUDNN installation steps

  1. Check the ~/.bashrc
export PATH="/usr/local/cuda/bin:$PATH"
export LD_LIBRARY_PATH="/usr/local/cuda/lib64:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.8/lib64/

2. Copy CUDNN the right way

sudo cp -av include/cudnn*.h /usr/local/cuda/include
sudo cp -av lib64/libcudnn* /usr/local/cuda/lib64
sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*

This should fixed the not a symbolic link problems!

Fix DuckDB out of memory error Export Database Parquet

I’m using the latest DuckDB 0.10.0 and receive memory error when exporting database with Parquet Format. I did with CSV and its work fine.

Memory configuration also set like :

SET memory_limit = '50GB';
SET max_memory = '50GB';
PRAGMA memory_limit=50GB;

This still trigger OOM. The only solution that works is 

SET preserve_insertion_order = false;

Hope this help you in solving memory error using DuckDB.

Fix Tensorboard in VSCode repeating could not install tensorboard package.

Tensorboard and VSCode is already well-integrated. However, there is a slightly problem when running it using the latest version.

Tensorboard is installed, prompted to install repeatedly. It keep re-appearing to ask installing Tensorboard session package with the same result :

Could not install tensorboard. If pip is not available, please use the package manager of your choice to manually install this library into your Python environment

Apparently, the major culprit is VSCode using different Python interpreter than the selected kernel in notebook. In this case, I’m using Anaconda with specific environment that already have tensorboard installed. To solve this, the solution is very straightfoward.

Solve ASUS WRX80 SAGE ensure to connect the 8-pin power please enter setup to recover bios setting fatal error

This is the most frustated problem I have encountered when using Asus Pro WS WRX80E-SAGE SE WIFI Motherboard Pro WS WRX80E-SAGE SE WIFI. The issue appeared when I changed the BIOS settings to enable the “SR-IOV” feature with the hope of solving USB devices not detected and avoiding adding “pci=nommconf” in GRUB.

Once, I rebooted, it suddenly its showing AMI Megatrend where everything was being initialized properly, and the last message was “ensure to connect the 8-pin power please enter setup to recover bios setting fatal error”. There is BIOS page at beginning to press F2 or Del, however it was not responsive and back to AMI page.

Solve TFX pip installation too long and slow

When installing TFX, I received error pip install tfx raises ResolutionTooDeep. During installation, its going over multiple different version of packages.

To solve this problem, I created requirements.txt with option to install necessary packages or all-packages that produced using pip freeze.

There are three options: TFX 1.10, 1.13 and the latest TFX 1.14.0

All the packages installation can be found here :

Depending on your needs, you can setup this using anaconda 

conda create -n 36 python=3.6
conda activate 36

2. Install NVIDIA python index

pip install --user nvidia-pyindex

3. Install Tensorflow 1.5 both GPU and CPU support

pip install --user nvidia-tensorflow[horovod]

Voila! Now you can run Tensorflow 1 using CUDA 11 or 12 on Ubuntu without problem.

Another alternative is using NVIDIA NGC.
