hash mismatch of resnet_v1.5_50-ml_c4.tar.gz file when building DLR #230

I am building from the source for x86, with:

git clone --recursive https://github.com/neo-ai/neo-ai-dlr.git
cd neo-ai-dlr
mkdir build
cd build
cmake ..

Then, I got the following error:

I changed the line 49 from cmake/Utils.cmake from:

         TIMEOUT 60  # seconds

to:

         TIMEOUT 600  # seconds

and then it built correctly. I suggest changing this parameter to avoid errors in slower connections.

Hey @denisyuji I also experienced that issue and it seemed to resolve itself, I didn’t realize it was related to the internet connection. Thanks for the timeout suggestion, I will increase it!
