I've been getting a warning when trying to install tensorflow on my windows pc, through the command prompt:
ERROR: Could not install packages due to an OSError: [Errno 2] No such file or directory: 'C:\\Users\\RCG\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\\LocalCache\\local-packages\\Python38\\site-packages\\tensorflow\\include\\external\\com_github_grpc_grpc\\src\\core\\ext\\filters\\client_channel\\lb_policy\\grpclb\\client_load_reporting_filter.h'
When looking this up, I found out that windows can't accept file paths longer than 250 words or so.
I've tried installing through anaconda but then I get a different error in pycharm: module not found (I've used an anaconda environment and tried installing through pycharm packages)
So I'm wondering if I can manually decide the file path for TensorFlow so windows will accept it.
Python was installed through microsoft store (otherwise pip wouldn't work)

I am able to successfully install Dlib with CUDA support in Windows 10 but getting an error during "import dlib" in my python code of computer vision project.
Environment: Windows 10, Python 3.7.6 (Anaconda), CUDA 11, CuDNN 10.2
Error Message:
>>> import dlib
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\ProgramData\Anaconda3\lib\site-packages\dlib-19.20.99-py3.7-win-amd64.egg\dlib\__init__.py", line 12, in <module>
from _dlib_pybind11 import *
ImportError: DLL load failed: The specified module could not be found.
This can be solved by copying the cudnn64_7.dll (available here: https://developer.nvidia.com/cudnn)
into the %CUDA_PATH%/bin directory (probably something like this: C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin)
I am able to find and fix this issue. CUDA 11 installation wasn't able to add few of the directories into the PATH environment variable (Windows 10). It was truncated due to the max length of 2048 characters. I have removed a few of the unused software paths from PATH value and after reinstallation, dlib 19.20 is working with CUDA 11 now.
I created an issue on DLIB Github under the following link which has more information regarding error logs and snapshots for this issue.
https://github.com/davisking/dlib/issues/2097
In my environment, the problem was due to an error somewhere in the build process that resulted code to load CuDNN dynamic libraries not being included in the generated file dlib/__init__.py despite having no build error. In my case the file always included this strange block of code:
if 'OFF' == 'ON':
add_lib_to_dll_path('cudnn-NOTFOUND')
add_lib_to_dll_path('C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.5/lib/x64/cudart.lib')
The second line's cudnn-NOTFOUND gave a clue of what happened with my build.
As I followed instructions on this page, copying all the binaries and include files to the right places within the CUDA directory, I only needed to modify the code to (similar to what Epic Chen's answer suggests but I got rid of the if clause and the bad code line):
add_lib_to_dll_path('C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.5/lib/x64/cudart.lib')
That workaround fixed the problem for me.
My configuration is CUDA 11.5, CuDNN 8.3.1.22, dlib compiled using Visual Studio 2019. The environment variable CMAKE_PREFIX_PATH to the CuDNN directory to get the compiler to find the include files and libraries.
If you are using Anaconda, uninstall dlib and reinstall dlib.
In anaconda command prompt, type
pip uninstall dlib
After successfully uninstalling, type
pip install dlib
It helped me fix the problem.
Try to check the __init__.py file which the error message indicate as below.
Your path is not the same as me.
In the __init__.py file, the if statement should be 'ON' == 'ON'
Besides, the following library paths must be correct. Your version may not be the same as me.
I am trying to get jupyterlab working using an environment handled by miniconda. However, starting from a fresh environment using python 3.8.0 and simply doing
conda install -c conda-forge jupyterlab
First lead me to an asyncio related error. I was able to solve it using this answer.
Now I am facing a DLL import error :
File "C:\Users\XXXX\AppData\Local\Continuum\miniconda3\lib\site-packages\zmq\backend\cython\__init__.py", line 6, in <module>
from . import (constants, error, message, context,
ImportError: DLL load failed: The specified module could not be found.
And I can't solve this. I tried using python 3.6.0 instead of 3.8.0. This did not work.
Any idea ? I am using Windows 10 build 1809 64 bits system.
I am trying to do the following in Python 3.7.1 on Windows
import sqlite3
but I get the following error message
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "c:\programdata\anaconda3\lib\sqlite3\__init__.py", line 23, in <module>

from _sqlite3 import *
ImportError: DLL load failed: The specified module could not be found.
I have searched for a solution to the problem for quite a while now to no avail. I have also successfully run pip install pysqlite3 on the Anaconda prompt, but the import still fails. What do?
I got this working on windows by downloading: the sqlite3 dll (find your system version)
And placing it into the folder: C:\Users\YOURUSER\Anaconda3\DLLs
(Depending on how you installed Anaconda, this may have to be placed into
the following folder: C:\ProgramData\Anaconda3\DLLs)
According to #alireza-taghdisian, you can locate the exact path of
your conda environments (where you need to copy the sqlite3 dll) by typing:
conda info --envs on your anaconda prompt.
Locate the sqlite3.dll file. In my case it was in following folder
C:\Users\Admin\anaconda3\Library\bin
where C:\Users\Admin\anaconda3 is the folder where Anaconda was installed
Add this to PATH in environment variables, and it should work then.
Try copying the sqlite3.dll from the
C:\Users\YOURUSER\anaconda3\Library\bin
folder to
C:\Users\YOURUSER\Anaconda3\DLLs
Please check https://github.com/jupyter/notebook/issues/4332
I added anaconda root/Library/bin to my PATH and now it works!
Add CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1 to your environment variables.
before executing the program, enter conda activate in your shell.
I had tried all above solutions But for me and my system I got to know that
I downloaded Python in C:\Python27 hence there is dll folder in python C:\Python27\DLLs
I installed Sqlite3.dll in my above dll folder
May be this solution will help you because it completely depends on where do you install your python
Happy coding :)
I put the sqlite3.dll in the path folder of my Python venv and still wont work. I suspected it is a path problem.
(In my case: E:\Virtual_Env\mini_zinc\env\Scripts)
I found in my case I messed up installation in a virtual evn, somehow using an anaconda python kernel within a Python venv.
I reinstall the Python Venv and check the python version after installed Env is correct (not the Anaconda python), then proceed with Jupyter Notebook (or Juyterlab) and works fine.
I was able to resolve this issue by putting sqlite3.dll file in the C:\Users<USERID>\AppData\Local\conda\conda\envs<ENV NAME>\DLLs.
Download sqlite3.dll file from https://www.sqlite.org/download.html
or copy it from C:\ProgramData\Anaconda3\DLLs\
I found the #elgsantos useful. But for those who are new to Python and Conda like me, I would like to add a little bit of details.
1- I use miniconda3 for creating new environment.
2- interestingly, I got two installation path on my computer for conda: the first one (the obvious) is located on "C:\Users\taghdisian\miniconda3". The second one is on "C:\Users\taghdisian\AppData\Local\r-miniconda". The latter is the primary path that you need to copy your sqlite3 files into the envs folder. I copy them in the "C:\Users\taghdisian\AppData\Local\r-miniconda\envs\sdr3.9\DLLs" in which the sdr3.9 is one of my virtual Condo environment.
you can locate the exact path of your conda environments (where you need to copy sqlite3) by typing the conda info --envs on your anaconda prompt.
I hope this help.
got the same error while loading the jupyter notebook from other conda prompt than "base" environment.

I currently have an error while installing tensorflow with python 3. Previously I had successfully installed tensorflow with python 2, and that was after I commented out several sections for ios/android. I decided to copy over the exact tensorflow files that worked for the python 2, and reconfigured the settings to suit it for python 3. Is this correct? Because I figured the configurations would be overwritten if I reconfigure the same files, and the edited files I require for TensorFlow to work will still be present.
Here is my error code:
error loading package 'bazel-tensorflow/external/bazel_tools/tools/build_defs/docker/testdata': Extension file not found. Unable to load package for '//tools/build_defs/docker:docker.bzl': BUILD file not found on package path.
I have tried many ways of installing psycopg2 after having installed PostgreSQL using the one-click installer, but anyway I try confronts me with the same import error in python: ImportError: dlopen(/Library/Python/2.5/site-packages/psycopg2/_psycopg.so, 2): Library not loaded: libpq.5.dylib
Referenced from: /Library/Python/2.5/site-packages/psycopg2/_psycopg.so
Reason: image not found
I am on Mac OS X 10.5.8. I am using Python 2.5. I installed PostgreSQL from the installer (I did not port it) and it installed in /Library). I added /Library/PostgreSQL/9.1/bin to the setup.cfg of the source psycopg2, as instructed in the INSTALL file and everywhere on the internet and then ran sudo python setup.py build and then sudo python setup.py install.
I also tried exporting /Library/PostgreSQL/9.1/bin to my path instead and running sudo pip install psycopg2. But the exact same problem occurred in all of these scenarii.
I would greatly appreciate some help with this.
Best
Marion
The problem is that at runtime the libpq.5.dylib file can't be found because it is not in one of the default locations searched by the dynamic (runtime) linker. Try to define the environment variable DYLD_LIBRARY_PATH before launching python. I am no MacOS X expert but something like:
export DYLD_LIBRARY_PATH=/Library/PostgreSQL/9.1/lib
will probably work.
