# Problem installing lambda stack: Failed to fetch python3-tensorflow-cuda Hello, just try to rerun the command, that happens sometimes. Just rerun the command make sure your device has a stable internet connection. TLDR: Rerun install command. --- # Cannot apt --fix, potentially conflicting packages Please try this: `sudo apt-get update && sudo apt-get dist-upgrade`. This should upgrade it properly then restart via: `sudo reboot` and it should work perfectly fine again. --- # OpenCV in lambda-stack - non-gpu? OpenCV GPU has to be installed manually and is to my knowledge not included in Lambda Stack. Here’s an article explaining it: [How to install OpenCV 4.2.0 with CUDA 10.1 on Ubuntu 20.04 LTS (Focal Fossa) | by Shitty Bots | Medium](https://medium.com/@sb.jaduniv/how-to-install-opencv-4-2-0-with-cuda-10-1-on-ubuntu-20-04-lts-focal-fossa-bdc034109df3) --- # CUDA 10.1 Upgrade for Lambda Stack Hello, are you planning CUDA 10.1? Are you working on it already? I would really need it now for TF 2.1 and up and I really don’t want to install manually. Leon --- # Unable to uninstall tensorflow Lambda stack installs the packages with apt. You can uninstall with `sudo apt autoremove python-tensorflow` --- # Import numba fails For updates, do `sudo apt install python3-numba` or if you want to keep the version you can install it via `pip3 install numba`. Best, Leon --- # Unable to enter desktop reinstall the nvidia driver and then install the ubuntu desktop again. Remember to disable nouveau in the bootloader. Best, Leon --- # The TensorFlow library was compiled to use AVX2 instructions, but these aren't available on your machine - Solving this issue Yea your cpu is pretty old. Your CPU just doesn't support AVX2. You have to uninstall the tensorflow cpu version and install tensorflow-gpu. That should probably work. --- # Lambda-tensorflow-benchmark on a tensorbook? No actually no reason for that. You didn’t really give much information about what you did run. Maybe some more information would be helpful. --- # Tensorbook - Ubuntu 18 No sound Try `sudo ubuntu-drivers autoinstall` --- # Upgrade Jupyter 4.4 to latest That’s good. Have a great day. --- # Upgrade Jupyter 4.4 to latest Do `sudo install python3-jupyter` --- # Item-based Recommendation I don't have one. But if you want to you can join our discord server where we share a lot of information about Machine Learning Research. [Lambda Deep Learning Community](https://discord.gg/UYP93sN) --- # Stuck at "Configuring libcudnn7" - can't accept the license (resolved) Yes sorry that I did just read that, I would like to answer quicker. Currently that’s a cuDNN problem. Hopefully they fix it. Best, Leon --- # Tensorbook reboot and show black Can you enter tty with `CTRL+ALT+F3`? --- # Lambda Tensorbook Specifications Yes activate it in the Boom and check in Ubuntu under Settings then Devices and then Thunderbolt. Check that full access is checked there. --- # Lambda Tensorbook Specifications Yes but it comes down to your monitor. They only power specific Laptops up to a certain amount to f power. --- # Stucked at ubuntu logo Type exit and then go to the main grub menu and start ubuntu. If that doesn't work go to advanced options and select the first option then. In case it still doesn’t work, please message me on Discord. My name is Leon Nowsden on there and I am online 24/7. [Lambda Deep Learning Community](https://discord.gg/acZQRrk) --- # Desktop windows 10 Cuda issue Then I am sorry. I don’t have an idea right now. Leon --- # Desktop windows 10 Cuda issue Ehm this is looking like a BIOS failure. Use the default bios settings. Make sure that you installed the UEFI version of Windows and maybe reinstall all the drivers. Overall I can't recommend a multi gpu rig in windows for Tensorflow… it's really buggy especially with conda. Install everything with pip... --- # Downgrade to Cuda 9 Just install CUDA9 from the CUDA archive. Then reboot and delete CUDA10 from path. --- # Experiencing some technical issues with my new TensorBook That's a common problem. I had that too. But since the last Ubuntu update, it was solved. Just update Ubuntu 18.04 as far as possible. --- # Accessing lambda stack libraries from Tensorflow Probably something went wrong with PyCharm. Try `python3 your_file_name_in_the_correct_dir.py` --- # I am trying lambda-stack on my tensorbook and it says unable to locate package lambda-stack Something went wrong when you added the repo. Just do this: ```bash LAMBDA_REPO=$(mktemp) && \ wget -O${LAMBDA_REPO} https://lambdalabs.com/static/misc/lambda-stack-repo.deb && \ sudo dpkg -i ${LAMBDA_REPO} && rm -f ${LAMBDA_REPO} && \ sudo apt-get update && sudo apt-get install -y lambda-stack-cuda ``` --- # Any CPU recommendations for Enterprise DL and ML Is AMD also a choice? --- # Tensorbook Max fan issues and battery usage Can you try `htop` and then read out the CPU usage. and then kill the process. --- # Reg: Installing Suse Enterprise Linux / Windows 10 via (VM) Nah it works fine with a KVM. --- # 404 Not Found [IP: 52.218.209.35 80] Yes it worked fine [@sabalaba](https://deeptalk.lambda.ai/u/sabalaba) --- # Using the Stack on Other OS's Sure just try it. I don't experiment any more. --- # Using the Stack on Other OS's No it’s just Ubuntu with Xfce installed on top. Leon --- # Using the Stack on Other OS's Yes Ubuntu with xfce works fine but I always had problems with other distros. --- # 404 Not Found [IP: 52.218.209.35 80] Hello, I am trying to install Lambda Stack on Ubuntu 18.10 and I am always getting this error.
